Webhooks

We don't send webhooks to API callers today. Everything an agent needs to know comes back on the request, on a stream, or from a call it makes.

To know	Instead of a webhook
When a model answer is done	Stream it and wait for response.completed: Stream the answer
When an OpenAgents chat is done	Read GET /v1/threads/{id} until thread.working is false
When a Coder run is done	Read openagents coder chat --json until the finished line: Run Coder headless
How much you have left	GET /v1/agents/me or GET /v1/key: Read your plan and usage
That a payment went through	The PAYMENT-RESPONSE or Payment-Receipt header on the paid answer
