A deterministic Base token safety card from Blockscout, DexScreener (derived) and Honeypot.is plus the Base RPC: what the contract is, who controls it, who holds it, where it trades, and whether a simulated buy/sell round-trips, with rule-based risk flags and a 0-100 score. No LLM. Informational only. Price $0.05 per call, paid with USDC over x402.

The cheapest way to look up a Base token: name, symbol, decimals, total supply, holder count, price, liquidity, pool count, largest pool, FDV and 24h volume, from Blockscout and DexScreener. Deterministic, no LLM, seconds per call. It is the data half of token_check; for contract ownership, holder concentration and a honeypot simulation, buy that instead. Informational only. Price $0.005 per call, paid with USDC over x402.

Everything an agent needs before touching a Base token, in one call: the deterministic safety card (contract, ownership, holder concentration, market, honeypot simulation, rule-based risk flags and a 0-100 score), the DefiLlama pools its symbol appears in with their TVL and APY, a sourced brief on the project written from its own site and Wikipedia with verbatim quotes (or none, when nothing verifiable is found), and a written verdict — avoid, caution or acceptable — whose reasons must each name a field of this report, checked in code, and whose verdict is overruled when it contradicts the risk score. Ask an optional question and it is answered from the same data. Informational only, not investment advice. Price $1.00 per call, paid with USDC over x402.

Snapshot of one DeFi protocol by DefiLlama slug: TVL by chain, category, 1d/7d change, audits, refreshed every 5 minutes from DefiLlama's protocol summary. Price $0.01 per call, paid with USDC over x402.

DeFi yield pools from DefiLlama, normalized and filterable by chain, project, symbol, stablecoin and min TVL; refreshed every 5 minutes. Price $0.02 per call, paid with USDC over x402.

The current odds of one Polymarket market and how they moved: give a market slug, a 0x condition id or the question as free text and get the YES and NO prices, the last trade, the implied probability, liquidity and volume, and the 24-hour and 7-day change against the derived store's daily closes, from Polymarket's public Gamma API. Deterministic, no LLM, seconds per call; a keyed market that does not exist is refused before payment, a free-text question that matches nothing is answered as not_found with the nearest candidates. A market price is not a forecast; informational only. Price $0.01 per call, paid with USDC over x402.

A ranked list of Polymarket markets from a derived store under deterministic filters: status (open, resolved or all), a category (an event tag with at least 200 resolved markets), a minimum lifetime volume, closing within N days, or the biggest 7-day movers up or down; sorted by volume, closing date or move; up to 50 rows with the question, tags, end date, resolution, volume, last close, 7-day change and days to the end. At most 500 candidates are ranked per request. No LLM, no free text. History and current prices, not advice. Price $0.05 per call, paid with USDC over x402.

Fetch one public web page (buyer-supplied URL, no login walls, robots.txt honoured) and return its main content as clean Markdown with title and word count. Price $0.02 per call, paid with USDC over x402.

Same as /v1/scrape/markdown plus a structured summary (≤200 words), key points and entities produced by an LLM from the page text. Price $0.04 per call, paid with USDC over x402.

Wallet hygiene for one Base address: every token it holds, each marked honeypot, dust, batch-airdropped, name-spoofed, ok or unknown, with the reasons (Honeypot.is simulation per token, capped at 25; pool liquidity; holder counts; the sender that batch-delivered them). Tells an agent which balances to ignore and never approve. Deterministic, no LLM. Price $0.05 per call, paid with USDC over x402.

Extract checkable factual claims from buyer-submitted text or a public URL, and verdict each one — supported, contradicted, unsupported or unverifiable — against Wikipedia and any buyer-supplied source URLs, with verbatim quoted evidence and links. Informational only. Price $0.05 per call, paid with USDC over x402.

Crypto and markets headlines matching your words, from twelve fixed public RSS/Atom feeds (CoinDesk, The Block, Decrypt, Cointelegraph, The Defiant, DL News, Blockworks, Bankless, Polymarket, CNBC, Bloomberg, Financial Times) refreshed every ten minutes: whole-word, case-insensitive search over titles and summaries within the last 1-168 hours (default 48), newest first, deduplicated, up to 50 items with title, link, publisher, published time and a short summary. Headlines as published, links to the source, no LLM. Informational only. Price $0.01 per call, paid with USDC over x402.

The daily YES-price history of one Polymarket market from a derived store of on-chain fills (the MIT-licensed dump before 2026-07-21, the public daily API after): give a market slug, a 0x condition id or a numeric id and a number of days (1-365, default 90) and get the series of daily closes with fill counts and volume, plus a summary: open, high, low, last, 1-day and 1-week change, days to the end date and the volume over the window. A market the store does not hold is refused before payment. Deterministic, no LLM. History, not a prediction. Price $0.02 per call, paid with USDC over x402.

Has a Polymarket market resolved, and how? Give a market slug, a 0x condition id, or the question as free text: you get the status (open, resolved, voided, unknown, not_found), the winning outcome and payout vector, when it closed and by which mechanism (UMA status, resolver), how many days after its end date, the last traded price and best bid/ask, and the event's categories, from Polymarket's public Gamma API. Deterministic, no LLM, seconds per call; a free-text question that matches no market is answered as not_found with the nearest candidates. A record of what happened, not a prediction; informational only. Price $0.05 per call, paid with USDC over x402.

Replay one fixed, published rule over resolved Polymarket markets from a derived store of on-chain daily closes: favorite_hold (buy the side at or above p on its first such day), longshot_hold (buy the side at or below p), late_entry (buy the favourite N days before the end date) or momentum_1w (buy in the direction of a one-week move). Pick a category (an event tag) and a date range; you get hit rate, mean and median return, drawdown, Brier score, a calibration table by entry price, results by year, a sample of matched markets and the exact method. Deterministic, no LLM, no buyer code. History, not a prediction; informational only. Price $0.25 per call, paid with USDC over x402.

What people are saying about your words on two public forums, deterministic and without an LLM: Hacker News stories and comments (via the Algolia HN Search API) and Polymarket event comments (via the Gamma API) within the last 1-168 hours (default 48), whole-word and case-insensitive, newest first, deduplicated, up to 50 items with the text (at most 300 characters), a link, the author's public handle and the time; counts per source and each source's ok flag. Public posts as written by their authors; not advice. Price $0.01 per call, paid with USDC over x402.

Everything to check before one swap on Base, in one call: the rule-based trade gate on the token (pass, caution or block with every reason), a scan of the buyer's own wallet for airdrop spam, honeypots and lookalikes when a wallet is given, and whether the token sits among the trending pools right now. The verdict is the gate's; the rest is context beside it. Deterministic, no LLM. Price $0.10 per call, paid with USDC over x402.

A sourced brief on any topic: 150-500 words of Markdown in which every paragraph cites the pages it was written from, plus the key facts as verbatim quotes with the URL each came from.

Price $0.10 per call, paid with USDC over x402.

One rule-based verdict before a swap on one Base token: pass, caution or block, with the reasons and the numbers that tripped them — Honeypot.is buy/sell simulation and taxes, pool liquidity and age, holder concentration, contract verification and ownership, and a name-spoof check against the canonical tokens. Deterministic, no LLM; a pass is not a guarantee. Price $0.05 per call, paid with USDC over x402.
