# Context.dev: Contextdev Get Change

> Get a change. Context.dev Contextdev Get Change reference includes SDK V2 and CLI requests, input constraints, response fields, and Deepline cost.

Get a change.

<Info>
  Tool ID: `contextdev_get_change`
</Info>

## Run this action

Use the TypeScript SDK for a single call. Put `ctx.tools.execute(...)` inside a Play when the call should be durable, scheduled, or run across a CSV.

```ts theme={null}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'contextdev_get_change',
  {
    "change_id": "change_123"
  },
);

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

### CLI

```bash theme={null}
deepline tools execute contextdev_get_change --input '{
  "change_id": "change_123"
}' --json
```

## Example response

The SDK exposes this shape at `result.toolResponse.raw`. Values below are representative.

```json theme={null}
{
  "data": {
    "mode": "web",
    "id": "id_123",
    "monitor_id": "monitor_123",
    "run_id": "run_123",
    "target_type": "page",
    "change_detection_type": "exact",
    "title": "VP of Engineering",
    "summary": "example",
    "detected_at": "2026-01-15T12:00:00Z",
    "url": "https://example.com/resource",
    "tags": [
      "example"
    ]
  }
}
```

Use `deepline tools get contextdev_get_change --json` for the latest machine-readable contract.
