Check before you pay: GET https://verified-catalog-lookup.withgrokbot.workers.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. Never pays. Skip = price mismatch, wrong asset/network, payTo differs from the listing, or a missing/malformed 402. JSON: /v1/skips.json · all receipts: /v1/receipts. Facts only, not endorsements.
★ Featured mismatch #b5e13e8271 (permalink): listed $0.001 on eip155:84532, 402 asks $0.001 on eip155:8453 → skip.
