  • verify_businessIs this company or domain legit?No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Is 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. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.05 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/business over HTTP. Same price on either transport.
  • verify_claimIs this claim true?No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Is 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. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.25 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/claim over HTTP. Same price on either transport.
  • verify_freshnessWebsite uptime and change check: is this URL up right now, and has the page changed?No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Website 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. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.02 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/freshness over HTTP. Same price on either transport.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Crypto 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. Free tier is unsigned and rate-limited. For a cryptographically signed attestation with no daily limit ($0.02 USDC), add an x402 payment header to THIS SAME tool call (PAYMENT-SIGNATURE for v2, X-PAYMENT for v1) or POST /verify/price over HTTP. Same price on either transport.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
