> List the websites that use a given technology, optionally filtered by country and first-seen date. Includes inputs, outputs, SDK V2 examples, and Deepline cost.

List the websites that use a given technology, optionally filtered by country and first-seen date.

> [!NOTE]
>
> Tool ID: `builtwith_lists`

## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'builtwith_lists',
  {
    "tech": "example"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute builtwith_lists --input '{
  "tech": "example"
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "NextOffset": "example",
    "Results": [
      {
        "D": "example",
        "FI": 123,
        "LI": 123
      }
    ]
  }
}
```

Use `deepline describe builtwith_lists --json` for the latest machine-readable contract.

## Input reference

## Deepline cost

* Pricing model: `fixed` (per call).
* Estimated Deepline credits: `0` per pricing unit.
* Provider-native pricing may still exist outside Deepline credit billing.
