### Illustrative output fields

Derived from the sample above for orientation only. These fields are not a fixed response schema.

| Path | Observed type | Example |
| --- | --- | --- |
| `blocks` | `array` | 3 items |
| `blocks` | `array` | 3 items |
| `has_more` | `boolean` | true |
| `page` | `integer` | 1 |
| `per` | `integer` | 24 |
| `total` | `integer` | 189 |
| `total_pages` | `integer` | 8 |

## Execution behavior

A `200` response completed inline. A `202` response was queued; poll `GET /jobs/{id}` until the job reaches `completed` or `failed`. Use an `Idempotency-Key` when retrying must not create a duplicate logical job.
