### Illustrative sample output

This redacted fixture is an example, not a fixed response schema.

```json
{
  "blocks": [
    {
      "class": "Link",
      "created_at": "about 1 month ago",
      "href": "/block/47265787",
      "id": 47265787,
      "image_url": "https://images.are.na/[redacted:token]==?bc=0",
      "source_url": "https://www.mangkupurba.net/",
      "title": "Mangkupurba",
      "updated_at": "5 days ago"
    },
    {

```
### 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 |
| `total` | `integer` | 189 |

## 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.
