Be careful. 3 of mr-river3.makar52nn2016.workers.dev's endpoints are rated Avoid right now: they were down a lot, took a payment and didn't deliver, or changed payout wallet without explanation. Check the specific endpoint before paying it.
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.
