FDA advisory-committee (AdCom) votes: every drug/biologic advisory committee meeting from 2024 forward, with the committee's exact vote tallies extracted from the official minutes PDFs (verified against the PDFs) -- one row per (meeting, vote question). The tally (vote_yes/vote_no/vote_abstain), the verbatim question, which answer was the product-favorable one, and whether the favorable side won; plus sponsor, drug, indication, committee, center, meeting status, and links to the minutes/transcript/briefing materials so any number can be checked at the source. A meeting with no tally is still a row -- vote_evidence says why (minutes not posted yet vs discussion-only vs not held), which is the difference between 'no data' and 'no vote'. Minutes land MONTHS after meetings, so recent meetings sit at minutes_not_posted until FDA publishes; rows re-label automatically when materials change. The forward calendar (scheduled meetings) is included. AdCom votes precede FDA decisions by weeks-to-months and FDA usually -- not always -- follows them. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing. Note: meetings are sparse (a few per month), so short date windows are often legitimately empty.

Connectivity and API-key check against the Alphanume API. Returns the API's status and version. Call this first if any other tool errors, to distinguish a bad/missing API key from a dataset-specific problem.

Buyback announcements: US-listed companies telling the market they will (or may) repurchase their own common stock, read from 8-K filings and their press releases. One row per 8-K that announces something NEW; event_type says what: a new repurchase authorization, an increase / extension / renewal (including a raised buyback target), an accelerated share repurchase, an issuer tender offer, a Rule 10b5-1 repurchase plan, or a program being completed, terminated or suspended. event_date is the announcement date the filing states (falling back to the 8-K period of report, then the filing date); filed_at is when the 8-K reached EDGAR and is the point-in-time clock. Served per row: ticker, cik, company_name, accession_no, a one-sentence event_description, authorized_amount_usd (for an increase: the increment when the filing states one, the new total when it states only that), authorized_shares for share-denominated programs, pct_of_market_cap (announced dollars over the market cap on the last session before the filing, in percent), expiry_date, replaces_prior_program (1 replaces / 0 in addition / NULL silent), remaining_prior_amount_usd (capacity the filing says was left under the prior or existing program), confidence and last_updated. Only first announcements are served. A later filing that restates an announcement already in the feed (the earnings release two weeks after the 8-K, an 8-K/A) and mentions of actions more than 45 days old are withheld, so a company's $50B authorization appears once, not every time it is repeated. Rows the labeler scored under 0.75 confidence are not served. Requires an Alphanume Pro API key. There is no date clamp on this route: a Pro key sees the full history. Honest limits, stated plainly. These are ANNOUNCEMENTS: an authorization is permission, not a commitment, and how much was actually repurchased is not in this dataset. authorized_amount_usd is NULL when the size is stated only in shares or not at all -- 10b5-1 plans and completions usually state none. pct_of_market_cap is NULL without a dollar size or market-cap history and is suppressed above 100. One event per filing: when an 8-K announces an authorization and a 10b5-1 plan under it, the authorization is the row. Not covered: issuer tender offers filed only on Schedule TO-I, foreign private issuers (6-K), and non-traded REIT / fund redemption plans (deliberately excluded -- those are investor liquidity, not buybacks). A small share of real announcements buried in long earnings releases is missed. History starts 2024-01-01. Default order: newest event_date first, then ticker, so the first page is the most recent announcements. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's cursor_date, cursor_ticker and cursor_id back to fetch the next page.

Corporate default events labeled from SEC filings: answers "which public companies just defaulted on an obligation, and on what terms?" One row per default event: ticker, event date, source filing URL, plus enriched fields extracted from the filing text -- event type, the obligation's name and type, creditor name, principal outstanding, amount accelerated, missed payment amount, stated default date, grace period end, whether acceleration was declared, and a confidence score with the supporting evidence quote. Fields are null where the filing text did not explicitly support them. Use it for distressed screening, credit event studies, or monitoring a date range for fresh defaults. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

US digital-asset enforcement, one normalized tape across the three agencies that bring it: SEC litigation releases and administrative proceedings, CFTC enforcement press releases, and DOJ criminal announcements, 2024+. One row per (action, respondent): what was alleged (multi-category), statutes cited, tokens/assets involved (real JSON arrays), monetary relief with its stated basis, settled flag (three-state), listed-issuer linkage where the document itself states one, and a follow-up chain linking successive actions by the same agency against the same respondent (complaint -> consent order, indictment -> plea). The date window filters published_date (structural, the agency's announcement date); action_date is extracted from the document with its own precision enum. One matter can appear once per agency -- nothing links across agencies, by design. monetary_relief_usd repeats on each respondent row of one action; de-duplicate on action_key before summing. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Material cybersecurity incidents: every Form 8-K filed under Item 1.05 (the SEC cyber-disclosure rule, live since 2023-12-18) plus its 8-K/A amendments -- the entire population, ~80 filings and growing. One row per filing, with FOUR distinct date roles kept rigorously separate: incident discovered, materiality determined (both extracted from prose, with day/month/quarter precision enums), disclosed and amended (both structural EDGAR dates, never model-guessed) -- plus the intervals between them (investigation time, compliance-clock time, total latency). Flags are three-state: 1 = filing says yes, 0 = filing says no, NULL = filing does not say -- never collapsed. Amendments are separate rows linked to their original (original_accession_number, days_original_to_amendment); an incident with three 8-K/As is four rows. materiality_determined_date is sparse (~15% fill) because most filings simply do not state one. days_determination_to_disclosure is CALENDAR days; the SEC's deadline is four BUSINESS days -- adjust before compliance claims. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

S-1 dilution filings tracker: answers "which companies are registering new share supply, and where is each registration in its lifecycle?" One row per S-1 registration event: ticker, company name, filing timestamp, market cap at filing, whether the filing is dilutive and/or a resale, shares offered, whether/when it became effective (with days-to-effective), whether/when it was withdrawn, and the SEC accession number + filing URL for the source document. Use it to flag dilution overhang on small caps, track time-to-effectiveness, or build event studies around registration filings. Filters by ticker and filing-date range (no exact-date parameter on this dataset). Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Dividend-capture calendar and scorecard: answers "which ex-dividend events are coming up, and how has capturing this name's dividend actually worked?" One row per ex-dividend event: the full schedule (declaration/record/pay dates, cash amount, frequency, type, annualized dividend, capture yield), the ex-day price action (cum-day close, ex open/close, price drop and drop ratio at open and close, net capture %), and the recovery record (breakeven price, recovery status/date, days to recover, recovered-within 1/3/5/10/20-day flags). A drop ratio well below 1 means the stock historically falls less than the dividend -- the raw material of a capture strategy. Set upcoming=true for the forward ex-div calendar (default 7 days out, up to 120 via future_days); use `ticker` for one name's full capture history. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Earnings move track record: answers "does the options market systematically over- or under-price this name's earnings moves?" One row per earnings event per ticker: the pre-earnings ATM straddle price and implied move (% and $), ATM IV, the realized post-earnings return and absolute move, the over/under-pricing gap and move ratio, an `overpriced` flag, EPS estimate vs actual, plus running per-ticker history stats (events to date, hit rate of straddle overpricing, average implied vs realized move to date). Use it before an earnings trade: query `ticker` to see whether selling or buying the earnings straddle has historically paid on that name, or screen a `date` to review how yesterday's reporters resolved. `date` is the earnings date. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Adverse FDA regulatory actions disclosed in 8-Ks: Complete Response Letters, full and partial clinical holds, and refuse-to-file letters, 2024+, each graded by an explicit severity precedence rule with the evidence flags the grade depends on served alongside it (new-trial-required, manufacturing-related, resubmission-path, hold-lifted). Follow-ups and resolutions are linked per (issuer, drug program), so an original hold row answers 'was it ever lifted, and how long did it take'. By default only classified FDA events are returned (~196 rows); the ~1,520 audited not-an-event rows the full-text sweep also retrieved are available with include_rejects=true. The date window filters disclosed_date (the EDGAR filing date); event_letter_date is extracted with its own precision enum and days_letter_to_disclosure is the selective-disclosure measure -- on initial_disclosure rows only (on follow-ups it measures distance to the original letter). Selective disclosure is the headline caveat: a CRL disclosed only in a 10-Q, or never, is not here. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

SEC filing intensity: the number of EDGAR filings each company submitted per day. Corporate action leaves fingerprints in the filing stream -- financings, restructurings, activist involvement, and deal activity all show up as bursts of filings before the news is digested. One row per ticker per day: ticker, company name, date, filing_count. Screen filing_count_gte over recent dates to surface names with unusual filing bursts, or pull one `ticker`'s history to spot regime changes in its filing cadence. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and ticker back as cursor_date and cursor_ticker to fetch the next page. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Point-in-time historical market capitalization: daily market_cap and shares_outstanding per US ticker, as they were known on each date (no restatement, no survivorship bias). The backbone reference for size filters, cap-weighted baskets, and normalizing anything by company size in a backtest. Requirements: provide `ticker` OR at least one date filter. A single `date` with no ticker returns the whole market for that day; a date RANGE without a ticker is capped at 7 calendar days. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and ticker back as cursor_date and cursor_ticker to fetch the next page. Companion tool: list_market_cap_tickers shows which tickers exist and their first available date. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Lock-up expiration calendar: when insider and pre-offering shares become eligible for sale after a US IPO or follow-on offering, past and UPCOMING, with the size of the locked block versus the offering float. One row per lock-up tranche per offering, sourced from the final prospectus (SEC Form 424B4 / 424B1) filed the day after pricing. `date` (also served as expiration_date) = the lock-up anchor (normally the prospectus date) plus the lock-up length in calendar days; shares_sellable_from is the first NYSE session on or after it. A plain 180-day lock-up is one row (tranche_seq 1 of 1); a staggered release is several rows sharing accession_no with tranche_pct. lockup_type separates operating-company IPOs (typically 180 days) from follow-on offerings by already-public issuers (typically 60-90 days). Blank-check (SPAC) IPOs are excluded. History from 2021. Sizing: locked_shares is the prospectus-stated locked count where given, otherwise shares outstanding after the offering minus shares offered. float_shares_at_offering = shares sold in the offering (plus the over-allotment when its exercise is stated); locked_to_float_ratio = locked / float, so 3.0 means three times the offering float unlocks on `date`. locked_pct_of_outstanding is the same block as a share of total shares outstanding. Requires an Alphanume Pro API key. There is no date clamp on this route: a Pro key sees full history and the forward calendar. Honest limits, stated plainly. Early-release clauses are common in recent IPOs (a release tied to the first earnings announcement, a price-based release, or staged tranches); the row carries early_release_type and the verbatim early_release_terms, but v1 does not compute the earlier date -- treat `date` as the contractual outside date when early_release_type is not 'none'. The over-allotment exercise is unknown at prospectus time, so the float can be understated by up to 15%. ticker may be NULL for a few days on a brand-new IPO; first_trade_date is IPO-only (NULL on follow-ons); market_cap_at_offering is NULL until the cap history covers the ticker; rows are never dropped for missing enrichment. confidence (0-1) is a per-row quality signal for the extracted terms; 0.9 means every term was resolved by the deterministic parser. first_seen_at is when our pull first observed the prospectus (synthetic = filing time for rows backfilled before launch). Default order: upcoming expirations first, nearest to today first, then already-expired rows most recent first -- so the first page is the calendar of what happens next. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's cursor_date, cursor_ticker and cursor_id back to fetch the next page.

Coverage map for the historical market cap dataset: every available ticker with its first available date. Use it to check whether (and since when) a name is covered before querying get_historical_market_cap, or to enumerate the full point-in-time universe. No parameters besides the row cap.

Quant Galore Momentum Index constituents: the daily holdings of a rules-based 12-1 momentum strategy (long the highest-momentum US names, refreshed on a fixed schedule). One row per constituent per day: date, ticker, and rank (1 = strongest). History is point-in-time -- each day shows exactly what the index held then, so backtests are free of look-ahead. Use it to mirror the index, source high-momentum candidates, or study momentum portfolio turnover. Query a single `date` for that day's basket, or a range to see how the basket evolved. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Next-Day Movers: each trading day, the US equities a volatility model ranks most likely to make an outsized price move in the *next* session. Rows carry the ticker, the list date, and -- once the next session has traded -- the realized outcome (`return` = signed next-day return, `absolute_move` = unsigned magnitude), so the dataset doubles as its own scorecard. Use it to focus long-gamma / straddle / breakout attention on a short daily list, or to backtest the signal against realized moves over a date range. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Historical optionable universe: point-in-time snapshots of which US equities had listed options on each snapshot date, with the average number of days between listed expirations (avg_days_between -- lower means a denser expiration calendar) and a has_weeklies flag. Essential for honest options backtests: it tells you what was actually tradable *then*, not what is optionable today. Filter by snapshot date range; omit filters for the most recent snapshots first. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and ticker back as cursor_date and cursor_ticker to fetch the next page. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Pre-market drop risk: model-estimated probability of an intraday decline in US microcaps, published each morning before the open. Each trading morning, by ~09:25 ET and ahead of the 09:30 open, a RandomForestClassifier scores every microcap that actually traded in the pre-market session and this dataset serves the names ranked by modeled drop risk. Features are cut at a fixed 09:00 ET pre-market cutoff. prob_drop is P(intraday open->close return <= -5%); one row per (date, ticker), ordered by rank_for_date (1 = the highest-probability name that day). It measures the subset the model flags, not everything that moved overnight, and is built for researchers and traders analyzing pre-market activity in US microcaps. Requires an Alphanume Pro API key. There is no date clamp on this route: a Pro key sees the whole history, whatever dates it asks for. Sub-$1 names are featured, not filtered. Every row the model flags is published, each carrying a sub_dollar flag: pass min_price=1 for the legacy '$1 and up' screen, sub_dollar=1 (or max_price=1) to isolate the penny cohort, max_rank=5 for the day's top five. History before go-live (2026-08-31) is walk-forward simulated: generated retrospectively by re-running the walk-forward loop (train on strictly-prior rows only, then score that date). There is no look-ahead in the features or the training window, but rows dated before go-live are not a real-time publication record; rows from go-live onward are published live each morning before the open. Outcomes fill in late, never early. intraday_return_pct lands the same evening; return_lead_1d / return_lead_5d / return_lead_30d only once 1 / 5 / 20 NYSE sessions have elapsed -- NULL means not yet mature, or no exchange print existed at maturity (halts and delistings, which this microcap universe produces regularly). Three documented quirks kept for continuity with the training set: return_lead_30d is 20 trading sessions rather than 30 calendar days; return_lag_1m uses the 21-session price change over the price 252 sessions back (a legacy denominator quirk, so it is not a clean 1-month return); and the t_0..t_9 pre-market return grid is 0-filled, not NULL, when no print exists at or before that clock mark. Borrow and locate costs are NOT modeled. Shorting a sub-$1 microcap needs a locate that may be expensive or simply unavailable, and no number served here carries that cost. sub_dollar and min_price are the levers for filtering toward borrowable names. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and rank_for_date back as cursor_date and cursor_rank to fetch the next page.

Volatility risk premium screener: answers "are this name's options rich or cheap right now?" For every liquid US optionable equity, per trading day: ~30-day at-the-money implied volatility (iv) vs ~30-day realized volatility (hv), their spread (iv-hv) and ratio (iv/hv), plus daily cross-sectional percentile ranks and z-scores for each measure, option notional volume, and the ATM strike/expiry/spot used. Rows update intraday (is_final=0) and settle after the close (is_final=1). Use it to find overpriced premium to sell (high iv_hv_ratio / min_ratio_rank near 1), underpriced options to buy, or to track one ticker's premium history via `ticker`. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

PIPE / private-placement deal feed: US-listed issuers raising money through unregistered placements (PIPEs, registered directs with warrants, convertible notes and preferreds, equity lines / ELOCs, SEPA pre-paid advances), each deal graded 0-3 for how toxic -- how price-dependent and dilutive -- its terms are. One row per 8-K private-placement deal event: an announcement (the securities purchase agreement is signed and disclosed), a closing (funds received), an amendment or price reset, or a termination; event_kind says which. announce_date is the 8-K filing date and is the feed's clock; event_date and closing_date are the dates the filing states. A deal announced and later closed is two rows sharing ticker and cik under different accession_no values. Deal economics served per row: gross_proceeds_usd (or committed_capacity_usd for an equity line), shares_sold, price_per_share_usd, discount_to_prior_close_pct, price_basis (fixed / variable_discount_to_market / lesser_of / unstated) with the variable discount, lookback window and floor, reset_provision, warrant_coverage_pct with exercise price and term, has_prefunded_warrants, original_issue_discount_pct, the stated investors / investor type / placement agent / exemption, the resale registration deadline and (once filed) the resale S-1 / S-3 form and dates, and market_cap_at_announce_usd with proceeds_pct_of_market_cap. toxicity_score, the 0-3 scale, derived from the stated terms: 3 = variable-price conversion (priced off a discount to future VWAP / lowest close, or the lesser of a fixed price and market) or a VWAP-priced equity line -- dilution grows as the price falls; 2 = a ratchet / price-reset provision, or >= 100% warrant coverage at >= 15% discount to the prior close, or original issue discount >= 10%; 1 = any common warrants, or a >= 10% discount, or any OID, or an equity line without a stated pricing formula; 0 = fixed price at or above market with at most pre-funded warrants; NULL = the terms live in an exhibit v1 did not read. The grade summarizes structure, not the issuer's prospects: a 0 can still be a large raise by a struggling company, which is what proceeds_pct_of_market_cap is there to show. Requires an Alphanume Pro API key. There is no date clamp on this route: a Pro key sees the full history. Honest limits, stated plainly. v1 reads the 8-K body, not its exhibits, so a deal whose economics live only in the attached purchase agreement carries price_basis='unstated', terms_in_exhibit_flag=1 and a NULL toxicity_score -- filter min_toxicity to keep only graded rows, or read terms_in_exhibit_flag before treating a NULL as benign. Investor names are frequently undisclosed ("certain institutional investors"); investor_names_stated is what the filing says, nothing more. discount_to_prior_close_pct needs a Polygon daily bar for the prior session and is NULL for unlisted or brand-new tickers and for variable-priced deals. market_cap_at_announce_usd and proceeds_pct_of_market_cap are NULL when the cap history does not cover the ticker; resale_* columns are NULL until a resale registration is filed / effective. SPAC-related placements (a PIPE into a de-SPAC, trust-extension financing) are flagged with is_spac_related=1, not removed. Rows are never dropped for missing enrichment. confidence (0-1) is a per-row quality signal for the extracted terms. first_seen_at is when our pull first observed the 8-K (synthetic = filing time for rows backfilled before launch). Default order: newest announce_date first, then ticker, so the first page is the most recent deals. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's cursor_date, cursor_ticker and cursor_id back to fetch the next page.

IV Rank & IV Percentile (52-week): answers "is this name's volatility high or low *for itself*?" For each US optionable equity, per trading day: where current ~30-day implied vol and 20-day realized vol sit inside that name's own trailing-year range -- iv_rank/hv_rank (0-100 position between the 52w low and high), iv_percentile / hv_percentile (share of the past year's days below today), the 52w high/low/median levels themselves, and daily cross-sectional ranks/z-scores for context. Rows update intraday and settle after the close (is_final=1). The classic premium-selling timing filter: min_iv_rank=50 finds names in the upper half of their own vol range regardless of absolute vol level. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Reverse-split calendar: every US reverse stock split, executed and UPCOMING, with pre-split price, market-cap tier, and dilution/shelf cross-links. One row per (ticker, execution date), sourced daily from Polygon's reference splits feed. Because the feed carries future execution dates, upcoming=true is a genuine forward calendar (~40 scheduled splits at any moment); ~70-100 reverse splits execute per month, almost all sub-$1 microcaps curing a listing deficiency. first_seen_at records when the pull first observed the row (an announcement proxy; for rows backfilled before launch it is set to the execution date itself and is synthetic). Requires an Alphanume Pro API key. There is no date clamp on this route: a Pro key sees full history and the forward calendar. Research context, stated plainly: in the Alphanume anomaly sweep (2022-2026, matched-control event study), reverse-split names underperform controls by roughly -6%/-12%/-18%/-40% over the 21/63/126/252 sessions after execution (~60% of events negative; Kim-Klein-Rosenfeld 2008 found the same). That makes this a screening/avoidance signal -- e.g. exclude fresh reverse-splitters from long screens, or use the calendar to anticipate the event. It is NOT a tradeable short card: borrow on these names is scarce and expensive and is not modeled anywhere, the calendar-time short portfolio was statistically inconclusive net of costs, and the long-horizon numbers are survivor-conditioned (only ~47% of events still have a full price history 252 sessions out). No CAR columns are served; the feed is the product. Enrichment semantics. sub_dollar_flag marks names whose unadjusted close the session before the split was under $1 (the raw price is an internal input and is not served). market_cap_before / market_cap_tier are populated from 2024-01-02 (NULL earlier -- the cap history starts there). ratio = split_to/split_from (<1 = reverse; a 1-for-10 is 0.1); is_deficiency_candidate flags ratio <= 0.5, separating real consolidations from ADR-fee-style near-1.0 adjustments, which are served raw. dilution_link_flag/shelf_link_flag mark an S-1 or S-3/F-3 filing by the same ticker in the trailing 365 days (dilution links meaningful from 2026, shelf links from 2025 -- the linked datasets' own history floors). Upcoming rows carry NULL sub_dollar_flag until execution; OTC names outside the coverage universe may keep it NULL along with cap fields. Open-end mutual fund share adjustments are excluded at ingest; ETFs and closed-end funds are included. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's cursor_date and cursor_ticker back to fetch the next page.

SEC trading suspensions: every Section 12(k) order halting trading in a stock, 1995 to today -- the terminal-risk tape for dying OTC and small-cap names. One row per (order, issuer): who was halted, when trading stopped, when it could legally resume (first NYSE session after the order terminates), the cited reason normalized to a 4-value taxonomy, listing venue, and the order PDF URL. Bulk delinquency orders (2013-2021) name up to ~55 issuers under one release_number -- use issuer_count/issuer_index to collapse rows back to order level. Ticker is NULL where the order states none (most pre-2022 rows). resumption_at is when trading MAY resume; many suspended names never quote again. The SEC's suspension output collapsed after 2021: expect only a handful of orders per year since. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing. Note the newest event may be months old: short date windows can legitimately be empty on this dataset.

Shelf registrations: every S-3/F-3 shelf registration statement, amendment and automatic (WKSI) shelf, normalized into a point-in-time capacity ledger -- the upstream signal behind every dilution screener. One row per filing: ticker, cik, company name, form, shelf_type (new|amendment|automatic), capacity_amount in USD (NULL means an indeterminate/automatic shelf -- never a guessed number), securities covered, WKSI flag, is_resale (selling-stockholder registrations), EFFECT date, days_to_effective, a 3-year expiry estimate, 424B5 takedown count, and market cap / shares outstanding at filing. Authorization is not issuance: capacity_amount is what the shelf REGISTERS, not what was sold. Screen date_gte over recent weeks for fresh shelf capacity, filter shelf_type=new + is_resale=0 rows for primary dilution risk, or pull one `ticker`'s history. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and accession_number back as cursor_date and cursor_accession to fetch the next page. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

S&P 500 risk regime: a daily binary classification of whether the US equity tape is in a risk-on or risk-off state. One row per trading day: date and risk_regime label. Deliberately minimal -- it is designed to be the overlay/kill-switch input to other strategies (e.g. only run momentum or premium-selling in the favorable regime), not a dataset you mine on its own. Query the latest date for the current regime, or a range to backtest a regime-filtered strategy. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

De-SPAC lifecycle: one row per SPAC business combination tracked from the definitive-agreement announcement through registration, definitive proxy, shareholder vote, exchange listing and completion (or termination / trust liquidation). Every row carries the SPAC's own symbol (prior_ticker), the combined company's symbol as soon as a filing names it (new_ticker -- the definitive proxy does so in most deals, weeks before the close), warrant ticker, exchange, SPAC / target / new company names, and the dated milestones: announced_date, meeting_date, record_date, vote_approved_date, listing_filed_date, expected_close_date and expected_trading_date (each with a *_basis column saying whether the date was stated in a filing or derived), closing_date, trading_commencement_date, terminated_date, plus next_event_date / next_event_type for what comes next. Completed rows also carry the closing financials (redemption shares and dollars, trust remaining, PIPE, gross proceeds, pro forma shares, enterprise and equity value), a confidence score and the supporting evidence quote. `date` is the SEC filing date of the filing that set the row's current status (for completed deals: the closing 8-K). `ticker` is the symbol trading for the deal today (new_ticker once listing is pending, otherwise prior_ticker). Fields are null where no filing supported them; quality_flags lists any rule that altered or withheld a value. Use status=pending&upcoming=true to see de-SPACs before the new symbol trades, ticker=<SPAC symbol> to follow one deal, view=history to replay what was known on a given date, or status=completed with a date range for the classic redemption-rate event study. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

SPX 0-DTE strike band: for each trading day, a model-derived intraday range (lower_strike, upper_strike) that same-day S&P 500 index options are expected to stay within, plus the instrument it applies to. One row per day. Use it to structure 0-DTE trades -- e.g. sell iron condors with short strikes at or beyond the band, or fade band breaches -- and to backtest how often the band held over a date range. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Ticker sector/industry classification: maps every covered US ticker into Alphanume's own 11-sector / 25-industry scheme (derived from SIC codes, but normalized into groups actually useful for trading -- e.g. 'semiconductors' and 'software' are separate industries under 'technology'). One row per ticker: ticker, alphanume_sector, alphanume_industry. Use it to group any other Alphanume dataset by sector, build sector-neutral baskets, or pull all names in one industry. Look up one `ticker`, or filter by `sector`/`industry` to enumerate a group. No date dimension and no tier restriction -- the mapping is current-state.

Vol-of-Vol Index: answers "how unstable is this name's volatility itself?" For each US optionable equity, per trading day: the coefficient of variation of its ~30-day implied vol (iv_vov) and 20-day realized vol (hv_vov) over the trailing month (std/mean of the last 21 observations), the underlying trailing mean and std, and a daily cross-sectional ranking of the most vol-unstable names. Rows update intraday and settle after the close (is_final=1). High vol-of-vol names are where vega risk is most treacherous (and where vol dislocations appear); low vol-of-vol names have sticky, well-behaved vol surfaces. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

Wikipedia attention tracker: daily page views of each covered company's Wikipedia article, with a 30-day rolling average and a relative 30-day z-score. Retail and media attention shows up in Wikipedia lookups before (and during) big price moves -- a z-score spike means the name is suddenly being researched far more than its own baseline. One row per ticker per day: ticker, company name, date, raw views, avg_30d, zscore_30d. Screen zscore_30d_gte=3 over recent dates for fresh attention spikes, or pull one `ticker`'s history to line attention up against price. Pagination: results are capped at 50,000 rows per request; when the response has has_more=true, pass next_cursor's date and ticker back as cursor_date and cursor_ticker to fetch the next page. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.
