| ----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `200` | The write result. `action` is `updated` when a near-duplicate document (at or above `similarity_threshold`) was updated in place instead of creating a new one; `force_create: true` always creates.                                           |
| `400` | Invalid request. `issues` names the offending field(s).                                                                                                                                                                                        |
| `401` | Missing, invalid, or expired API key.                                                                                                                                                                                                          |
| `403` | The key lacks a required scope.                                                                                                                                                                                                                |
| `409` | Conflict — either the creation ceiling was reached for this organization (`agent_limit_reached`), or a request with the same Idempotency-Key is still in flight (`idempotency_in_progress`); retry the latter after the first attempt settles. |
| `422` | The Idempotency-Key was already used with a DIFFERENT request body (`idempotency_key_reused`). Reuse a key only to retry the identical request.                                                                                                |
| `429` | Rate limit exceeded.                                                                                                                                                                                                                           |
