X402 API — questions

Answers built from our own checks of this server.

Why is there no uptime for X402 API?
X402 API runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @x402-api/mcp-server was installed 41 times last week.
How do I connect X402 API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @x402-api/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use X402 API?
The npm package @x402-api/mcp-server was installed 41 times in the last week. Week over week that is +11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is X402 API open source?
Yes — it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
