## Tools
- verify_business - Verify a business or domain is real and established before your agent pays an invoice, onboards a vendor, or trusts it. Checks RDAP registration age, DNS (A/MX/NS), email posture (SPF/DMARC), and HTTPS reachability, and returns a signed attestation with a 0-100 trust score and evidence URLs. Free tier is unsigned and rate-limited; the paid HTTP endpoint POST /verify/business ($0.05 USDC via x402) returns a cryptographically signed attestation suitable for audit trails. Endpoint: https://402oracle.com/mcp
- verify_price - Confirm a crypto asset's price before your agent trades, quotes, or settles on it. Cross-checks Coinbase, Kraken, and OKX for a median and flags divergence when sources disagree. Returns a signed attestation. Free tier is unsigned and rate-limited; the paid HTTP endpoint POST /verify/price ($0.02 USDC via x402) returns a cryptographically signed attestation suitable for audit trails. Endpoint: https://402oracle.com/mcp
- verify_freshness - Check that a URL is live and current before your agent acts on its contents. Returns HTTP status, Last-Modified/ETag, a content SHA-256, and whether it changed versus a prior hash. Returns a signed attestation. Free tier is unsigned and rate-limited; the paid HTTP endpoint POST /verify/freshness ($0.02 USDC via x402) returns a cryptographically signed attestation suitable for audit trails. Endpoint: https://402oracle.com/mcp
- verify_claim - Fact-check a single factual claim against web evidence before your agent relies on it. Returns a verdict (supported / contradicted / insufficient), a confidence score, and citations, as a signed attestation. Free tier is unsigned and rate-limited; the paid HTTP endpoint POST /verify/claim ($0.25 USDC via x402) returns a cryptographically signed attestation suitable for audit trails.
