Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| PROOF_API_KEY | — | yes | Proof Holdings API key (Bearer). Optional: without it the server runs in public mode, where account creation, login and public verification tools work and every other tool asks for a key. Create one in the dashboard at https://proof.holdings. A key minted from inside a session with create_api_key takes effect only once it is set here and the server is restarted — this value is read at startup and has no runtime setter. |
| PROOF_BASE_URL | — | — | API base URL. Defaults to https://api.proof.holdings. |
