11 of api.polls.karbach.digital's endpoints are rated Proceed: reliable in monitoring with a stable price and payout wallet, and the best ones delivered in a real paid test. Grades are per endpoint, so look up the one your agent is about to pay.
Lumière PayCheck checks every endpoint about every 30 minutes: does it answer with a valid x402 quote, is the price and payout wallet stable. Then we pay some of them for real and check the response against what the listing promised. Failures are re-tested before they count. How it works.
Yes, for free. Call check_payment (API or MCP) with the endpoint, amount and payTo from the 402 quote, and pay only if it returns allow. Check an endpoint now.
