Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
series
get_series
One economic data series: the latest print, the forecast, the surprise in standard deviations, and the history.
list_series
Every US economic data series Helious tracks (CPI, payrolls, GDP and so on) with its slug for get_series.
access
get_access_info
What your current tier can do, the full plan ladder, and the exact steps to tell your user when you need more: make a free account, get a key, or subscribe.
auctions
get_auctions
US Treasury auction results, measured by Helious at the close: the high yield, the tail against the when-issued yield, bid-to-cover against the tenor's twelve-auction average, who bought (indirect, direct, dealer), and the desk's strong, in line or weak verdict. Pass tenor to ask about one part of the curve, like 10-year-note or 30-year-bond, which is what you want for 'how did the last 10-year auction go'. The tail is the number that answers whether an auction was good or bad and Helious is the only free source that publishes it.
board
get_fx_board
FX momentum scorecard: seven major currencies scored against the basket. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.
correlations
get_correlations
Cross-asset correlation matrix (stocks, bonds, dollar, gold, oil) over 30 to 120 day windows. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.
curve
get_curve_history
Past curve regime changes: every flip with its time, what it flipped from, and how the session closed.
document
get_document_digests
The desk's read of FULL central bank documents, not headlines: FOMC minutes and Fed/ECB speeches read end to end. Each digest carries a summary, what is genuinely new versus what the market already knew, key findings with their market consequence, a hawkish/dovish committee lean, and quotes verified word for word against the source document. Minutes carry no bond or equity direction on purpose: they describe a meeting about three weeks earlier, so the desk states the lean and declines the market call. Delayed 60 minutes without a paid key.
earnings
get_earnings
US mega-cap earnings: when a company reports, whether that date is confirmed or still an estimate, whether it prints before the open or after the close, the consensus EPS, and once it lands the reported EPS with the beat or miss. Pass symbol for one name, like AAPL. This is the tool for any question about a company's earnings date or EPS.
economic
get_economic_calendar
Economic releases with forecasts, prior values and the actual once it prints, plus Fed speakers and auction times. Defaults to yesterday through the next 7 days; widen days_back and days_ahead to see more, or filter to one country like US, EU, GB or JP.
fed
get_fed_roster
Who is on the FOMC: governors and presidents, who votes this year, their lean, and their upcoming speeches.
feed
get_feed
The posts Helious publishes: scored releases, auction results, board updates, the daily brief and live squawk lines. Posts carry helious_read, the desk's plain-English line on why it matters. Depth follows your plan (1 day keyless, 7 days free, 12-24 months paid, 10 years Ultimate). Optional q filters by word; categories narrows to chosen lanes. Delayed 60 minutes without a paid key.
hormuz
get_hormuz_transits
Ships through the Strait of Hormuz per day, split tanker and cargo, measured by Helious from live ship tracking.
market
get_market_context
START HERE for any 'why is the market doing this' question. One call gives the whole cross-asset board (equities, the Treasury curve, FX, volatility, commodities), every scored economic release behind it, and the Helious desk's read on what is actually driving the session: whether it is event-driven, flow-driven or quiet, the evidence that read rests on, and the regime yields and stocks have actually been trading in. Use this before the individual board tools: it saves five calls, and it characterises the session rather than leaving you to guess a cause. Market data: answers with numbers on Pro and Ultimate.
nasdaq100
get_nasdaq100
The NASDAQ-100 ranked best to worst on the session: price, change and sector for every stock. Pass symbol to ask about ONE company instead, like AAPL or NVDA, and you get its price, its move on the session and where it ranks on the board today. Equities are market data: live on Pro and Ultimate, upgrade steps instead of numbers below.
rate
get_rate_odds
The odds of a Federal Reserve rate cut or hike at each remaining FOMC meeting, priced from fed funds futures. THIS IS THE TOOL for 'what are the odds of a cut in September', 'is the Fed cutting', 'what is priced in for the next meeting' or 'how many cuts this year'. Gives the probability per meeting, the implied effective rate after each one, and the total move priced across the whole path. Computed by Helious from settlement prices against the effective fed funds rate, not the target midpoint.
rates
get_rates_and_curve
US Treasury yields, the 2s10s and other spreads, and the curve regime (bull or bear, steepener or flattener) with the time it flipped. Prices are live on Pro and Ultimate, one hour behind on Starter, and answer with upgrade steps on the free tiers.
squawk
get_squawk_sessions
Live events Helious transcribed in the last week (Fed pressers, briefings), one entry per event.
treasury
get_treasury_curve
The whole US Treasury curve in one call, 3M bill to 30Y bond with daily closes: live points on Pro and Ultimate, one hour behind on Starter, upgrade steps instead of numbers on the free tiers.
vol
get_vol_board
Implied volatility board: VIX and the other vol gauges with their one-year percentile. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.
yield
get_yield_closes
Official 17:00 New York Treasury yield closes per session, as Helious recorded them. Opens on Starter and above.
