x402 from zero

Mogami

A one-person Java stack for x402: client SDK, Spring Boot starter and a free Base facilitator.

Checked 11 October

Our view

Competent work for Java shops that has stopped: no human commit since 13 May. The hosted facilitator still answers, and the official x402 repository now has its own Java SDK, which removes much of the reason to wait for it.
