Self-Maintaining APIs: founder validation breakdown
Original RFS by Harsha Gaddipati. Source: Y Combinator Requests for Startups.
The RFS in plain English
YC is interested in APIs that communicate changes, keep documentation current, prevent integration breakage, and maintain themselves as products evolve.
Why now
More software is assembled through APIs while AI agents increasingly write integrations that need reliable contracts and change awareness.
IdeaCheck angle
This is a natural IdeaCheck fit: painful, technical, frequent, and tied to measurable developer time lost when integrations break.
Founder trap to avoid
API maintenance tools can become nice-to-have documentation polish unless they sit directly in the release, SDK, and customer support workflow.
A concrete idea to test
A self-maintaining API layer that watches code changes, updates docs and SDKs, warns customers, and creates migration guides automatically.
