# Stream Response in cURL

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

After [creating a new custom agent](/developer-resources/tutorials/custom-agent/create-custom-agents), you can call and use it via the [Custom Agent API](/api-reference/custom-agent), which 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": "your_custom_agent_ID",
    "input": "Summarize today\'s top AI research headlines and cite sources.",
    "stream": true
  }'
```

Below is the summary excerpt of the streaming events:

```text theme={null}
id: 0
event: response.output_item.added
data: {"seq_id":0,"type":"response.output_item.added","response":{"type":"chat_node.answer","output_index":0,"delta":"The capital of France is Pa"}}

id: 1
event: response.output_item.delta
data: {"seq_id":1,"type":"response.output_item.delta","response":{"output_index":0,"delta":"ris."}}
```
