POST/priceNo price listedCrypto price check: the current spot price of Bitcoin (BTC), Ethereum (ETH), Solana (SOL) or any token ticker in USD, cross-checked across five exchanges (Coinbase, Kraken, OKX, Binance, CoinGecko). Returns the median price, the spread between venues and a divergence flag, as a signed price oracle attestation your agent can cite. Use it before your agent trades, quotes, values a portfolio or settles on a token price. Needs at least two live quotes; a ticker no venue lists is not charged.
POST/freshnessNo price listedWebsite uptime and change check: is this URL up right now, and has the page changed? Fetches the URL and returns the HTTP status, Last-Modified and ETag headers, a SHA-256 fingerprint of the content, and whether it changed versus a hash you pass in. Use it to check a site is live, detect stale data, monitor a page for changes, or decide whether to invalidate a cache before your agent acts on what it says. Returns a signed attestation.
POST/claimNo price listedIs this claim true? Fact-check a single factual claim or statement against live web evidence before your agent relies on it. A fact-checking oracle, hallucination guard, and grounding and citation check for misinformation review: returns a verdict (supported / contradicted / insufficient), a confidence score, and source citations, as a signed attestation your agent can cite.
POST/businessNo price listedIs this company or domain legit? Business and domain verification (KYB) for vendor screening, supplier checks and scam or fraud review: domain age and registrar from RDAP, DNS (A/MX/NS), email security (SPF/DMARC) and HTTPS. Returns a verdict and a 0-100 trust score with evidence URLs, and flags newly registered or thin-infrastructure domains, a common scam signal. Use it before your agent pays an invoice, onboards a vendor or trusts a site. Signed attestation. Bulk: /verify/business/batch.
POST/business/batchNo price listedBulk domain and company check: domain age, registrar and legitimacy for up to 5 business domains in one call. Screen a prospect or lead list, qualify companies before outreach, check vendor and supplier lists, or clear invoice batches. Same checks as /verify/business per domain (RDAP domain age, DNS, SPF/DMARC, HTTPS) with a verdict and 0-100 trust score each, as one ES256-signed attestation. Flat $0.15 per batch: 40% below the per-domain price of single calls at a full batch.
