| --- | --- | --- |
| `keyId` | UUID | Your key id. |
| `challengeGeneration` | integer | The current challenge generation. |
| `proofState` | string | `pending`, `accepted` or `failed` — a proof that did not verify or came too late. After five failed proofs, ask Anis staff to restart the enrolment. |
