# Resolve the credential issuer's DID document

`GET /.well-known/did.json`

The W3C DID document for Baselayer's credential issuer. Every credential names its issuer as a `did:web` identifier; verifiers resolve that identifier to this document and match the credential's signing key id against `verificationMethod`. Keys publish ahead of activation and remain published through rotation overlap, so verifier caches stay warm. Unauthenticated; cacheable for one hour.

## Response `200`

The issuer's DID document (W3C DID core).
