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.

how.is alternatives FAQ

Prices are for the endpoint we check; other routes and what you get per call differ, so check the provider before paying.

How are these alternatives ranked?

Same category, ranked by x402 grade, then uptime from our own daily unpaid checks, then x402 score, valid x402 share and median response time. Price is shown but never used for ranking, and paid placement never changes the order.

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.
