About
Fay is a research-focused product with webhook support for developers who want to connect research jobs to their own applications. Based on the documentation, it exposes events for task status changes, completed output, and errors, so you can react to research lifecycle updates in real time.
Fay’s webhook layer is straightforward and practical: it reduces the need to poll the API and gives you structured notifications with request and conversation IDs. That makes it a good fit for workflows that need to queue follow-up actions, store results, or handle failures automatically.
Executes tasks you assign, one step at a time, within narrow domains.
