Feedback is enabled by default. On an eligible paid response, the SDK mints a feedback_id locally and exposes it in the Forge-Feedback-Id header. Supported JSON object bodies can also receive feedback_id, feedback_url, and a short rate_this_call hint. The x402 402 challenge can point agents to the free rating route without changing payment terms. An agent can submit a quick rating with GET /feedback/rate or a detailed rating with POST /feedback:
outcome is fully, partially, no, or not_evaluated. An optional issue explains a poor outcome; note is at most 280 characters and should contain no user data. GET /feedback describes the form, and GET /feedback/summary returns public aggregates. These routes are free, but feedback submissions contact the Forge collector to validate the ID and store the rating. Choose a different basePath if your service already owns /feedback. Set feedback: false (Node or Python) to disable invitations and feedback routes while keeping background telemetry. Options.
