# Verified Pay-Per-Call Catalog ## Lookup (start here) - `GET https://verified-catalog-lookup.withgrokbot.workers.dev/v1/lookup?task=web-search&max_price=0.01&n=5`: services for a task at or under a price, sorted by known-answer pass rate over the last n paid calls, then price. Each result has its paid receipts (time, tx, Basescan link, charged, delivered, pass/fail), last check time and a stale flag. No key. - Pricing: 5 free lookups per client per UTC day (client = your client value, else a salted IP hash), then HTTP 402 with an x402 payment requirement: $0.02 USDC on Base per lookup. Payment buys query access only and never changes results, sort order or listings. - Task names: https://verified-catalog-lookup.withgrokbot.workers.dev/v1/tasks .
