  83. 972s.io/api/crypto/token-priceCurrent spot price and market data for crypto assets. Pass ids as comma-separated CoinGecko asset ids (e.g. bitcoin, ethereum, solana, usd-coin — lowercase id, not ticker symbol; up to 25 per call) and optionally vs (comma-separated fiat/crypto quote currencies, default usd). Returns per-asset price, market cap, 24h volume, and 24h percent change, plus the data timestamp. Live market data past any training cutoff. Price data by CoinGecko.$0.003 Base135 ms2 payers100% up
  84. 972s.io/api/dns/lookupResolve a hostname over public DNS and return parsed records. Query: host (required FQDN), types (comma-separated: A,AAAA,MX,TXT,NS,CAA,SRV,CNAME,PTR,SOA — default A,AAAA,MX,TXT,NS), resolver (cloudflare|google|quad9|opendns, optional). Returns one normalized JSON shape per record type with per-type error pass-through. Reserved/local TLDs (.local, .internal, .invalid, .test, localhost) are rejected. 4s per-query timeout.$0.0025 Base161 ms2 payers100% up
  85. 972s.io/api/url/mapDiscover the URLs a page or sitemap points at in a single fetch. Point it at an XML sitemap or sitemap-index and it returns the <loc> URLs; point it at an HTML page and it returns the <a href> links — auto-detected. URLs are resolved to absolute, de-duplicated, fragment-stripped, and http(s)-only. `limit` (1-2000, default 200) caps the count; `sameHostOnly` keeps only links on the same host. Single SSRF-guarded fetch, no JavaScript, stateless — NOT a recursive crawler: to go deeper, call map again on a child sitemap or a discovered page. Returns { url, finalUrl, source: "sitemap"|"links", count, capped, urls }.$0.0027 Base144 ms2 payers100% up
  86. 972s.io/api/finance/figi-searchFree-text search for securities across global exchanges via OpenFIGI. Give a query (company name, ticker, description) and optionally narrow by exchCode (e.g. US), securityType, or marketSector (Equity, Corp, Govt, Mtge, Muni, Pfd, Comdty, Index, Curncy). Returns relevance-ranked matches with FIGI, composite/share-class FIGI, name, ticker, exchange, security type, market sector, and description, plus a `next` cursor for paging (pass it back as start). Free, open symbology (Bloomberg OpenFIGI). Distinct from finance.figi (exact identifier → FIGI): this is discovery by name/keyword.$0.0036 Base122 ms2 payers100% up
  87. 972s.io/api/bank/lookupFDIC-insured US bank directory lookup. Lookup by name (fuzzy match), FDIC certificate number, RSSD ID, or state.

  88. 97agent402.tools/api/x402/seller-trustTrust evidence for any x402 seller origin: is it indexed, does its manifest parse, how many tools does it publish, which chains does it actually advertise, how many settled calls has it been observed receiving on-chain, and would our own Smart Order Router spend buyer money on it. Returns the router's gate field by field, so a refusal is explainable. Never fetches the seller at call time - this is our accumulated crawl and settlement evidence, not a liveness probe.$0.005 Base280 ms2 payers100% up
