# AgentFit API

> Developer documentation for the AgentFit public API. AgentFit audits public API
> documentation against a 30-criteria AI-readiness rubric and returns a deterministic
> 0–100 report over HTTP, the CLI, or a remote MCP server. No LLM calls at run time.

## About
AgentFit scores a documentation site across six categories — Discovery, Page artifacts,
API spec, Content, Hygiene, and Agent Surface — with concrete HTTP evidence for
every criterion. The same rubric this site is built to satisfy. See https://agentfit.dev for the
audit service.
