```

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

```json
{
  "coverage": "public_http_popular_technologies_only; global source-reported live-site counts; localized counts excluded",
  "retrievedAt": "2026-09-18T08:43:43Z",
  "sourceUrl": "https://trends.builtwith.com/",
  "technologies": [
    {
      "liveSites": 8531474,
      "name": "Shopify",
      "url": "https://trends.builtwith.com/shop/Shopify"
    },
    {
      "liveSites": 505226,
      "name": "Magento",
      "url": "https://trends.builtwith.com/shop/Magento"
    },
    {
      "liveSites": 51480405,
      "name": "WordPress",
      "url": "https://trends.builtwith.com/cms/WordPress"
    }
  ]
}
```
### Illustrative output fields

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

| Path | Observed type | Example |
| --- | --- | --- |
| `coverage` | `string` | public_http_popular_technologies_only; global source-reported live-site… |
| `retrievedAt` | `string` | 2026-09-18T08:43:43Z |
| `sourceUrl` | `string` | https://trends.builtwith.com/ |
| `technologies` | `array` | 3 items |
| `technologies` | `array` | 3 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.
