    "https://example.com/",
    "https://www.iana.org/help/example-domains"
  ]
}
```

## Response

Successful output is returned in `results[0].data`.

Raw platform output is intentionally open-ended and may evolve with the upstream source.

### Illustrative sample output

This example shows one response. Values and optional fields vary with the data available.

```json
{
  "results": [
    {
      "elapsed_ms": 640,
      "output": {
        "content_type": "text/html",
        "final_url": "https://example.com/",
        "parsed": {
          "markdown": "# Example Domain\n\nThis domain is for use in documentation examples.",
          "parser": "html_dom"
        },
        "status_code": 200,
        "url": "https://example.com/"
      },
      "success": true,
      "url": "https://example.com/"
    },
    {
      "elapsed_ms": 120,
      "error": {
        "code": "upstream_error",
        "message": "The requested data could not be retrieved. Try again later."
      },
      "success": false,
      "url": "https://missing.example/"
    }
  ],
  "stats": {
    "failed": 1,
    "requested": 2,
    "succeeded": 1
  },
  "warnings": [
    "batch_partial_failure"
  ]
}
```
### Illustrative output fields

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

| Path | Observed type | Example |
| --- | --- | --- |
| `results` | `array` | 2 items |
| `results` | `array` | 2 items |
| `stats` | `object` | 3 fields |
| `stats.failed` | `integer` | 1 |
| `stats.requested` | `integer` | 2 |
| `stats.succeeded` | `integer` | 1 |
| `warnings` | `array` | 1 items |
| `warnings` | `array` | 1 items |

## 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.
