Your agent needs an `agent_api_key`. Create an agent at `http://localhost:8000` (web UI) or via:

```http
POST http://localhost:8000/v1/agents
Authorization: Bearer {user_api_key}
Content-Type: application/json

{"name": "my-bot"}
```

Response:
```json
{"id": "agt_...", "api_key": "btx_agt_...", "name": "my-bot"}
```

Store `api_key` as your `agent_api_key` for all subsequent calls.
