Get the technology stack a company uses from its domain, optionally checking for specific technologies.

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

## 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(
  'findymail_lookup_technologies_by_domain',
  {
    "domain": "example.com"
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute findymail_lookup_technologies_by_domain --input '{
  "domain": "example.com"
}' --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": {
    "domain": "example.com",
    "technologies": [
      {
        "name": "Example",
        "category": "example",
        "subcategory": "example"
      }
    ]
  }
}
```

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