scrapecheck.fly.dev/verify-json

JSON tier (deterministic, no LLM): verifies a claimed value lives at a named JSON path in a public endpoint's response, by independent double re-fetch. Use it for machine-readable API responses; for HTML pages use /verify. Claim keys are paths (data.items[0].price). Type-strict; volatile values return unverifiable, never a guess. Public HTTPS JSON only. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.
