The official sources we monitor

The primary sources behind every audit we produce. Bookmark them — you don't need us to check them by hand. We exist for the weeks you skip.

• OpenAPI Specification — the spec format we diff for breaking changes
• oasdiff (open source spec differ) — DIY spec diffing — the manual version of what we automate
• Wayback Machine APIs — how past legal/pricing page states are reconstructed
