Every agent-payable API.

Live on-chain spot market for one Hyperliquid-listed token by symbol (e.g. HYPE, PURR) or @index: mid/mark price, previous-day price, 24h USD and base volume, circulating and total supply, and market cap, quoted in USDC. Spot, not a perp — for funding/open interest use /api/v1/perps/{coin}; for major-coin fiat prices use /api/v1/crypto. From x402stock, a market & economic data API (x402, USDC).

The options chain for a US-listed underlying: every listed contract with its strike price, expiration date, call or put type, exercise style, contract ticker, and shares per contract. Filter with ?expiration_date=YYYY-MM-DD, ?contract_type=call|put, ?strike_price=, ?expired=true|false, and ?limit=. Use to discover which option contracts exist before pulling price history. From x402stock

Use to read one immutable archived day of a feed (sol.jlp, hl.perps, prestocks.markets, scores.squeeze, …): the exact payload the live endpoint returned that day, plus provenance (observed/captured/ingested timestamps + a content hash proving contemporaneous capture). Defaults to latest; ?date=YYYY-MM-DD for a past day, ?entity= on multi-entity feeds. From x402stock

Settlement fails-to-deliver for a US-listed stock from the SEC's semi-monthly data: the aggregate shares that failed to deliver on each settlement date, with the reference price, most recent first. A niche short-pressure and squeeze signal. ?limit= records (default 30). Sourced from SEC EDGAR. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.

Fetches a company's latest 10-K, 10-Q, or 8-K from SEC EDGAR and returns a structured JSON summary: a plain-language overview, the key risk factors, MD&A highlights, any forward guidance, and an overall sentiment label. Choose the document with `?type=10-K` (also 10-Q, 8-K). Built for agents that need the substance of a filing without parsing hundreds of pages of HTML. From x402stock

The native SOL balance and basic account state for any Solana address, read from the public ledger: lamports and SOL, whether the account exists, its owning program, executable flag, and data size. Pass a base58 address in the path. Keyless on-chain data — no Jupiter API, no account. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.

Company name, exchange, market cap, share class, SIC code, address, and other reference fields for a US-listed ticker. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

Pass the coin in the path (e.g. BTC) and tune with `?interval=` (default 1h), `?lookback=` candles (default 200, max 5000), or an explicit `?start=`/`?end=` epoch-ms range. Free on-chain DEX data (venue: Hyperliquid), no key. From x402stock

Get the latest available price for any US-listed stock: the most recent 1-minute bar close plus today's OHLCV, change, and previous close. Currently 15 minutes delayed; each response carries `is_delayed: true`. Real-time pricing lands when the data plan is upgraded. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

Schedule 13D/13G filings — triggered when a holder crosses 5% of a class — disclosing beneficial-ownership and activist stakes in a US-listed company, from SEC EDGAR. Per filing: the reporting person, filer-reported percent of class (can be <5% if held via derivatives), shares, voting/dispositive power, and (for 13D) the activist intent. `?type=13D|13G|all`, `?limit=` max 25. From x402stock

Pass a token symbol (e.g. HYPE, PURR) or @index and tune with `?interval=` (default 1h), `?lookback=` candles (default 200, max 5000), or `?start=`/`?end=` epoch-ms.

Returns filing date, item labels, and a link to the filing. Cap with `?limit=`. Use to track earnings releases, leadership changes, and material agreements. Sourced from SEC EDGAR. From x402stock

A `sections` map flags anything unavailable. From x402stock

Open, high, low, close, volume, and VWAP for a ticker's most recent completed trading day. One call returns one bar, handy for prior-close reference without setting a date range. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

Renders a finished one-page equity tearsheet PNG for a US-listed stock — not raw JSON to assemble. Fans out to profile, price, 1-year history, fundamentals, technicals and news, then draws a 1-year price chart with its 50-day average plus key stats (market cap, P/E, margins, dividend yield, 52-week range) and headlines. Returns the data plus a hosted `artifact.png_url`. From x402stock

The prosecution-history timeline for one patent application — pass the `{application}` number plus `?limit=` (max 200), newest first. Each event carries its date, USPTO event code, and description (office actions, allowance, grant, abandonment, etc.) — the momentum/risk read on where an application sits. Source: USPTO. From x402stock, a market & economic data API (x402, USDC).

Historical OHLCV price bars for one option contract over any date range.

Use for backtesting or charting a single option's price history. From x402stock

Use for time-series questions over the archive: how JLP AUM, Hyperliquid funding, a pre-IPO token premium, or a ticker's squeeze score evolved day by day. Per-day summaries (oldest first, ?from ?to ?limit, max 366) with capture provenance; payloads omitted — buy a full day via /archive/{feed}?date=. History accumulates daily and cannot be reconstructed retroactively. From x402stock

A country's macro profile in one call: latest GDP, GDP growth, GDP per capita, inflation, unemployment, population, government debt, current account, exports, and FDI, from the World Bank's World Development Indicators. Pass an ISO country code in the path (e.g. US, CN, IN, DE). International macro the US-only FRED/BLS endpoints don't cover. Source: World Bank (CC BY 4.0). From x402stock

What's inside an ETF or mutual fund, from its latest SEC N-PORT filing. Pass an ETF/fund ticker (SPY, ARKK) or CIK in the path.

Fund composition the 13F feed doesn't cover. From x402stock

Live on-chain account state for any wallet on the Hyperliquid perp DEX, by 0x address: account value, total notional, margin used, withdrawable; every open perp position (size, long/short, leverage, entry, unrealized PnL, liquidation price, margin); and resting open orders (up to `?limit=`, default 200; `open_orders_count` is the total).

Per notice: the insider and relationship, shares to be sold, aggregate market value, approximate sale date, broker, shares outstanding, and any sales in the past 3 months. A PROPOSED sale, not an executed trade. `?limit=` max 25. From SEC EDGAR. From x402stock

Daily short-sale volume for a US-listed stock: total volume, short volume, exempt and non-exempt short volume, the short-volume ratio, and a per-venue breakdown (NYSE, Nasdaq, ADF), most recent day first. A higher-frequency read on shorting pressure than bi-weekly short interest. Tune with `?limit=` (default 20). From x402stock, a market & economic data API (x402, USDC).

Backtests a simple rule on a US stock and returns a finished report PNG.

Returns full stats plus a hosted `artifact.png_url`. From x402stock

The exchange-reported short-interest history for a US-listed stock: total shares sold short, average daily volume, and days-to-cover for each bi-weekly FINRA settlement date, most recent first. A core short-squeeze and bearish-positioning signal. Tune how many settlements to return with `?limit=` (default 12). From x402stock, a market & economic data API (x402, USDC).

A company's recent SEC disclosure picture in one call: the filings index, insider transactions from Form 4 with a net buy/sell signal, material 8-K events by item code, and initial holdings from Form 3. The CIK is resolved once and shared across sections (faster than four separate calls), at a lower combined price. From SEC EDGAR; sections degrade independently. From x402stock

Initial beneficial-ownership holdings parsed from SEC Form 3 filings, the first report an insider files on becoming a director, officer, or 10% holder. Each holding carries the security, shares owned, direct or indirect ownership, and derivative terms. Complements Form 4 transactions. ?limit= filings (default 5). Sourced from SEC EDGAR. From x402stock, a market & economic data API (x402, USDC).

The largest holders of any Solana SPL token (top accounts by balance, up to 20), each with its token account, owner wallet, balance, and share of total supply — for holder-concentration and whale analysis. Pass a base58 mint or a known symbol (JUP, JLP, …); tune with `?limit=` (max 20). Read from the public ledger, no Jupiter API. From x402stock, a market & economic data API (x402, USDC).

Recorded ownership transfers (assignments) for one patent application — pass the `{application}` number. Each carries the reel/frame, conveyance text, received & recorded dates, assignors, assignees (with location), and the recorded-document link. A patent sale, collateral pledge, or M&A signal the price/filing feeds miss. Source: USPTO. From x402stock, a market & economic data API (x402, USDC).

Pass the pair in the path as BASE-QUOTE, e.g. EUR-USD or USD-JPY. Use for FX charting, backtesting, and macro/rate analysis. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

All markets in one Hyperliquid HIP-3 builder DEX (pass the dex id, e.g. `xyz`): 24/7 synthetic mark & oracle price, funding rate + APR, open interest, and day volume each. Covers equity perps (NVDA, TSLA), commodities (GOLD, BRENTOIL, COPPER), FX, and index perps. Oracle-priced proxies carrying funding — not the underlying's official last trade. List DEXs at /api/v1/hip3/dexs. From x402stock

Per-period financial statements (income statement, balance sheet, cash flow, comprehensive income) sourced from SEC filings, flattened to fact_key → value maps. Pass `?timeframe=annual|quarterly|ttm` and `?limit=`. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

A full AI-synthesized equity-research memo for one US stock in one call. Fans out across profile, fundamentals, technicals, short interest, insider activity (Form 4/144), 13D/G stakes, 8-K events, news and sentiment, then an LLM distils a balanced bull/bear case, valuation context, catalysts, risks and a per-signal read-out with an overall stance. Factual synthesis, not advice. From x402stock

The short-squeeze picture for a US stock in one call: bi-weekly short interest with days-to-cover, daily short-sale volume with short-volume ratio, and settlement fails-to-deliver, plus a computed signal pulling the headline gauges together. Replaces three separate calls (short-interest + short-volume + fails-to-deliver) at a lower combined price. Sections degrade independently. From x402stock

The stock price history endpoint. Returns historical OHLCV bars at the requested multiplier and timespan (minute, hour, day, week, month) between `from` and `to`.
