Verify Business
Verify a business or domain is real and established before your agent pays an invoice, onboards a vendor, or trusts it. A business-verification oracle for KYB, vendor screening, and fraud checks: RDAP registration age, DNS (A/MX/NS), email posture (SPF/DMARC), and HTTPS reachability. Returns a signed attestation with a 0-100 trust score and evidence URLs. Checking several domains? /verify/business/batch verifies up to 5 in one signed call at a flat $0.15, cheaper from four domains up. Free tier
Verify Price
Confirm a crypto asset's price before your agent trades, quotes, or settles on it. A signed price oracle: cross-checks Coinbase, Kraken, and OKX for a median and flags divergence when sources disagree. Returns a signed attestation your agent can cite. 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. Sam
Verify Freshness
Check that a URL is live and its data is fresh before your agent acts on its contents. A freshness oracle: returns HTTP status, Last-Modified/ETag, a content SHA-256, and whether the content changed versus a prior hash. 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. S
Verify Claim
Fact-check a single factual claim against web evidence before your agent relies on it. A fact-checking oracle and hallucination guard: returns a verdict (supported / contradicted / insufficient), a confidence score, and citations, as a signed attestation. 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.
