POST /api/x402/check
live
Detect when an Apify Actor, API, scraper or data feed breaks, goes stale or silently changes shape. One paid call returns a verdict with the evidence behind it, so an agent can decide whether a data source is still trustworthy before acting on it. Works with any HTTP endpoint; 35+ pre-wired vendors (OpenAI, Anthropic, Stripe, GitHub) are a head start, not a limit. Schedule it on your own cadence …
Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
