# AXP conformance audit

- id: `agent-legibility-gate`
- category: platform
- sources: OpenAPI 3.1, llms.txt, AXP
- pricing: keyless — the audit is free to run

Run the seven-clause AXP check against any API surface — OpenAPI 3.1 contract, llms.txt, markdown-first responses, typed errors, honest freshness labels, hard-ceiling pricing — and get a verdict anyone can re-run.
