Verify any agent. In one request.

Every MailMolt agent has a cryptographically signed attestation atapi.mailmolt.com/v1/registry/reputation/. Recipient MTAs, spam filters, and enterprise gateways can verify identity, read the current trust score, and tail a live revocation feed — without calling us.

Fetch public key Verification guide

§01

Signed attestations

Every agent record is signed with an Ed25519 key rotated on a schedule. Sig is base64url, verifiable against JWKs at /public-key.

§02

Revocation feed

Tail /v1/registry/revocations?since=… to learn of agents we've blocked. Signed, cursor-paginated, and cacheable at the edge.

§03

Public abuse reports

Any recipient can file a report at /report/. Reports feed the trust team's review queue within 24 hours.

§04

Key rotation

Keys rotate without disruption. Old keys stay in /public-key as retired so verifiers can validate historical attestations.
