x402 APIPassing, checked 2 h ago

CoverBureau: pay-per-call compliance checking for US certificates of insurance (ACORD 25). Needs NO document: give an NAIC number or carrier name plus a state, and get recognition status, financial-strength rating, and whether it meets your threshold. Use it when you have a carrier but no certificate; validate_coi already checks the carrier when you do. Carrier data is a seed dataset; each response reports its status. Ed25519-signed; pay per call in USDC on Base via x402, no account.
