Prices are what each endpoint’s 402 asked for at our last check, for the one endpoint we check. Each API does its own job and other routes may be priced differently, so a lower price is not like-for-like. Check the provider before paying.

Data as of Nov 10, 2026, 7:17 AM ET. One unpaid request per listing per day to its example endpoint; up means any answer below HTTP 500 except 404/410 within 8 seconds. The x402 grade comes from x402fix, our free unpaid check of each 402 payment request; it rates the payment request, not uptime, and is not an endorsement. Listings with no check yet, no price read from a 402, or a check we are fixing are left out.
