Key insight: Every API team runs CI/CD tests but almost none test 'does our documentation match what the API actually does'—this is a blind spot because it requires both schema knowledge and runtime testing, which no single tool owns today

The Problem

API documentation falls out of sync with actual endpoints constantly—developers ship breaking changes, clients hit unexpected errors, and teams waste hours debugging 'documented' behavior that no longer exists. Most teams only discover this when support tickets flood in.

Target Audience

Backend teams at startups and mid-market SaaS companies (especially those with public APIs or partner integrations), DevRel engineers, and API platform teams managing 10+ endpoints

Why Now?

API-first architectures are standard now, and AI can reliably compare schemas and responses—this was tedious to build manually but trivial with LLMs for schema diffing and alert rule generation

What's Missing

Existing API documentation tools are static (Swagger UI, Mintlify)—they don't continuously validate docs against reality. Monitoring tools focus on availability, not accuracy of documented behavior.
