Shares a payout wallet with 178 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Find out which x402 versions you are actually dealing with across a set of sellers. Reports challenges declaring a version you do not support, challenges declaring no version at all - where how to read the rest is a guess - and a set spanning more than one version, which means your client must implement each of them at once. Nothing is paid.

This payout wallet is shared: figures cover all 179 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
