x402 skillA
x402 is agent-read markdown (skill) from nirholas/three.ws: Search for new services and make paid API requests using the x402 payment protocol. Use when you don't have a clear tool to choose, search the bazaar. You can also use this tool if you or the user want to call an x402 endpoint, discover payment requirements, browse the bazaar, or search for paid services. This is the three.ws-native x402 stack (awal, USDC on Base) and is the default; defer to okx-agent-payments-protocol only when the user names OKX/OnchainOS, or the 402 is channel/voucher/sessio.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add nirholas/three.ws/x402@git:20260712.0ed36ddmdr add nirholas/three.ws/x402@sha256:564d8fa89afff757Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
