Check before you pay with PayScout (formerly Spot-Check): GET https://payscout.dev/v1/products/endpoint-spot-check?url=https://example.com/api/paid (optional &claimed_price=0.01; or POST JSON {"url":"https://example.com/api/paid"}) returns verdict pay|skip|recheck. 1 free/day, then $0.01-$0.25 USDC via x402 on Base (one tenth of the target's quoted price). Never pays the target.
Self-checked: One unpaid GET/POST per listed URL (listing's example params only if the bare URL 4xx'd), 5s timeout, SSRF-gated, at most 3 requests in flight per host. Never pays. Deduped by normalized URL (lower-case scheme/host, no default port/fragment/trailing slash, sorted query). Skip = no paywall (no 402), a malformed 402, price mismatch, wrong or unsupported network, a token other than canonical USDC, or a payTo that differs from the listing. Recheck = transient (timeout, network error, 5xx) or a free trial in use. JSON: /v1/skips.json · one receipt: /v1/receipts/<id> · by URL: /v1/receipts/by-url?url=<endpoint>. Facts only, not endorsements.
★ Featured mismatch #b5e13e8271 (permalink): listed $0.001 on eip155:84532, 402 asks $0.001 on eip155:8453 → skip.
