  }'

POST

/v1/certificates/issue

Issue a certificate, generate a PDF, and return the verification proof.

GET

/v1/verify/:certificateId

Check certificate status, hash, proof mode, and revocation state.

POST

/v1/certificates/:certificateId/revoke

Revoke a certificate and record the audit trail.

Bearer API keys

Store hashed sandbox and production keys with prefix-aware routing.

Webhook events

Prepare integrations for certificate lifecycle events.

Canonical JSON

Hash sorted metadata consistently across languages and systems.

Proof-aware reads

Resolve PDF sandbox or Base Mainnet production proof based on key mode.

Client sandbox proof is already connected

Sandbox keys skip crypto entirely, generate PDFs, and store verification history in Supabase. Production keys anchor on Base Mainnet after approval.
