What does your agent want to do?
A task-indexed buyer's guide to the 609 APIs at Agent402 - written from the agent's side of the call. Each row maps a real goal to the cheapest tool that solves it. Browse the full category-organized catalogue at /tools, walk the multi-tool workflows at /skills, or ask the discovery endpoint directly: /api/find?q=<your task>.
Research a public company
One call returns the latest 10-K/10-Q/8-K filings, recent insider trades, live stock quote, and current news headlines.
GET /api/edgar-filings?ticker=AAPLGet a snapshot of the US economy
Fresh FRED indicators (CPI, unemployment, Fed funds), Treasury yield curve, and FX rates - all from official feeds, no signup.
GET /api/cpi-yoyRead a webpage as clean markdown
Article extraction strips boilerplate to title + byline + body markdown. Use render if you need post-JS DOM.
POST /api/extractSearch the live web
Independent web search, with separate news and image surfaces - and an `answer` tool that returns a cited synthesis instead of a link list.
GET /api/search?q=federal+reserveTrack crypto markets
Live prices, market-cap rankings, history, and global dominance, batched in one request; when the shared upstream quota is spent the call answers 503 and is not charged.
GET /api/crypto-price?ids=BTC,ETHTrack equities
End-of-day US equity quote and daily OHLCV bars from a licensed three-venue consolidation. US equities only - for crypto pairs use crypto-price. Volume is those three venues, returned as venueVolume, never as a market total.
GET /api/stock-quote?symbol=AAPLDig into SEC filings
Ticker → CIK, recent filings, full XBRL financial-statement history per concept, insider trades, 13F holdings, IPO calendar, full-text search.
GET /api/edgar-filings?ticker=AAPL&form=10-KRun a domain or uptime check
DNS, TLS certificate inspection, WHOIS/RDAP, HTTP health, robots.txt and sitemap parsing - the boring infra primitives every agent eventually needs.
POST /api/http-check?url=https://example.comConvert or process a document
PDF → markdown, PDF page extraction/merge/rotate, images → PDF, PDF metadata. JSON ⇄ CSV/YAML/XML and markdown ⇄ HTML alongside.
POST /api/pdf-to-markdownPersist state across calls
Wallet-keyed KV with TTL and atomic counters. The wallet IS the identity - no signup, no API key. Grant access to other agents by their wallet.
POST /api/memoryPay another x402 seller
Decode HTTP 402 quotes, verify settlements on Base, check USDC balances, build EIP-3009 transfer authorizations. You sign - these tools never touch funds.
GET /api/x402-quoteFind a tool across every x402 seller
/api/route ranks this catalog and the outside sellers we index; /api/find resolves a task within this catalog and names related outside sellers. Candidates are shortlisted by how well they match the task, then ordered by crawl health, by distinct payers over the last 30 days, by price, by a discovery listing's curated flag and by slug length, shorter first; a judgment model can then pick the one that does the job from that shortlist, or decline them all, and when it is not consulted the shortlist order stands. Both are free, no payment.
