Every public API should have a feedback endpoint for agents

AI agents are increasingly using APIs, yet there is often no easy way for them to tell developers what went wrong. A post on Freek.dev argues that every public API should include a feedback endpoint to close that gap.

The reasoning is simple: when an agent misbuilds a request, fails to understand a field or gets an unexpected response, it should have somewhere to say so. According to the report, this feedback lets API owners see where agents get stuck, so problems can be spotted before they reach users.

The article notes that this is useful not only for debugging but also for improving API design. Feedback from agents can reveal which endpoints are hard to document and which responses cause confusion. The piece says developers should not underestimate this signal.

On the practical side, a small addition to existing infrastructure may be enough: a simple endpoint where an agent can send a short explanation and request details. According to the report, the real gain is that AI agents using the API make their problems visible instead of quietly giving up.
