# Stream Response in cURL

> Learn how to manage the stream response with the Express Agent API in cURL

The [Express Agent API](/api-reference/express-agent) can stream responses. This allows you to process data incrementally as it becomes available, rather than waiting for the full payload.

The following example shows how to manage a stream call of the Express Agent API with cURL:

```bash theme={null}
curl -N \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Accept: text/event-stream" \
  -H "Content-Type: application/json" \
  -X POST https://api.you.com/v1/agents/runs \
  -d '{
    "agent": "express",
    "input": "What is the capital of France?",
    "stream": true
  }'
```

Below is the summary excerpt of the streaming events for the input:

```javascript theme={null}
id: 0
event: response.created
data: {"seq_id": 0, "type": "response.created"}

id: 1
event: response.starting
data: {"seq_id": 1, "type": "response.starting"}
