Api Endpoint

attest-verify

Verify an attestation produced by /notarize (either the EIP-712 or the EAS off-chain form) — pure compute, no network and no keys. Recovers the signer and reports whether it matches this service's attestor, whether the EAS UID recomputes, and (if you supply the original body as payload_base64) whether its sha256 matches the attested hash.
