# BuiltWith: Domain Lookup

> Look up the technologies (tech stack) a website domain uses now or used historically, plus metadata, for one domain or up to 16.

Look up the technologies (tech stack) a website domain uses now or used historically, plus metadata, for one domain or up to 16.

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

## 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_domain_lookup',
  {
    "domain": "example.com",
    "domains": [
      "example.com"
    ],
    "live_only": true
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute builtwith_domain_lookup --input '{
  "domain": "example.com",
  "domains": [
    "example.com"
  ],
  "live_only": true
}' --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": {
    "Results": [
      {
        "Result": {
          "Spend": 123
        },
        "Meta": {
          "CompanyName": "Example Corp",
          "City": "San Francisco",
          "State": "California"
        },
        "Attributes": {}
      }
    ],
    "Errors": [
      {}
    ]
  }
}
```

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

## Input reference

Run BuiltWith domain lookup for one domain or up to 16 domains, returning technologies, metadata, and history.

| Name | Type | Required | Default | Details |
| - | - | - | - | - |
| `payload.domain` | `string` | No | — | Root domain or subdomain to inspect (for example stripe.com). |
| `payload.domains` | `array` | No | — | Optional multi-domain lookup. BuiltWith supports up to 16 domains here. |
| `payload.live_only` | `boolean` | No | — | When true, return only currently live technologies. Defaults to true. |
| `payload.no_pii` | `boolean` | No | — | Exclude names and email addresses from the response. |
| `payload.no_meta` | `boolean` | No | — | Exclude BuiltWith metadata such as company name, socials, phones, and ranks. |
| `payload.no_attr` | `boolean` | No | — | Exclude BuiltWith attributes data. |
| `payload.hide_text` | `boolean` | No | — | Hide technology descriptions, links, tags, and categories. |
| `payload.hide_dl` | `boolean` | No | — | Hide technology descriptions and links while keeping tags and categories. |
| `payload.trust` | `boolean` | No | — | Request trust data inline. This consumes an extra BuiltWith API credit per domain. |
| `payload.first_detected_range` | `object` | No | — | Filter technologies by first-detected date range. |
| `payload.last_detected_range` | `object` | No | — | Filter technologies by last-detected date range. |
