Examples
Provider metadata JSON: {"issuer":"https://id.example.com","authorization_endpoint":"https://id.example.com/auth","jwks_uri":"https://id.example.com/keys","response_types_supported":["code"],"subject_types_supported":["public"],"id_token_signing_alg_values_supported":["RS256"],"token_endpoint":"https://id.example.com/token"}
Expected issuer: https://id.example.com
Limitations
- Pasted JSON only; checks bounded core metadata, not full provider certification, TLS trust, keys or endpoint reachability. No requests.
- Maximum 100,000 UTF-16 units per field, 400,000 UTF-8 combined input bytes, 4 MiB output and 30 seconds in a local worker. Tool-specific bounds may be tighter.
- Generated snippets are source text inside the JSON download. They are never executed by this tool. Local inspection does not verify remote systems or establish standards certification.
