## 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(
  'hunter_discover',
  {
    "query": "software companies hiring engineers",
    "organization": {
      "domain": [
        "example.com"
      ],
      "name": [
        "Example"
      ]
    },
    "similar_to": {
      "domain": "example.com",
      "name": "Example"
    }
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute hunter_discover --input '{
  "query": "software companies hiring engineers",
  "organization": {
    "domain": [
      "example.com"
    ],
    "name": [
      "Example"
    ]
  },
  "similar_to": {
    "domain": "example.com",
    "name": "Example"
  }
}' --json
```

## Example response
