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

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

### CLI

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

## Example response

The static output schema lacks the details for a reliable example. Use `deepline describe smartlead_add_domain --json` for the complete live contract.
