Oct 5, 2026Two new x402 APIs for AI agents: API-freshness probing + DNT/GPC policy audit (2026-10-05)
/api/api-freshness HEAD-probes 10 conventional health/version endpoints (/health, /healthz, /ready, /api/version, etc.) and returns alive_count + version_hint + a 0-100 A-F grade. /api/dnt-gpc-policy fetches the target URL 3x (baseline, with DNT:1, with Sec-GPC:1) to detect server-side honoring of privacy signals + checks 5 privacy-policy paths for keyword mentions. Both $0.0005 per call via x402 USDC on Base.
