FA

Webhook-driven research notifications for your app

Fay can send real-time webhook events when research status changes, completes, or fails. It is useful if you want to trigger downstream workflows from research results instead of polling for updates.

    Rubric upgrade: agenticness v3.0 (8 dims, /32) → v3.1 (9 dims, /36). Adds Dim 9 (Operator Sovereignty), splits Dim 6 into 6a/6b lenses, tightens Dim 4 autonomous-retry distinction. Not a product change — score shift reflects new dimension + recalibrated rubric, not a change in the tool. Fanout suppressed.

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.

What to Know
