}Verify a signature proof (public)
Public endpoint (no credentials) that verifies a wallet signature proof by its public capability code (the proof_code, which starts with G). Returns JSON by default; with Accept: text/html it renders a branded verification page. Anti-enumeration: an invalid or unknown code returns the same generic 404. Shares the per-IP rate limit of the public verification endpoints. The signature and message hash are exposed because they are the material of the public proof (no PII).

}Path Parameters
Public capability code of the proof (starts with G).
Response
The proof verification result. valid is true only when the proof is signed, not expired and not revoked; verified_live reports the live cryptographic re-verification of the signature.
Available options:
issued, signed, expired, revoked
