Developers who found a service through an x402 directory and want to ship their own pay-per-call API quickly. Registration, deployment and listing steps (including the directory requirements that are not obvious) were done on 2026-10-02 for one real project. The paid settlement path was not exercised.
The paid path of the project this guide is based on has not been exercised end to end, because there were no test funds. Verify with a small real payment before you rely on any of it. Public analytics fetched on 2026-10-02 (x402watch) showed roughly 2,655 paid transactions per day across about 24,600 indexed services, with the top 25 endpoints taking about 92% of calls. A new seller should expect little or no organic traffic at first.
