facts402: x402 API finder + fact checks — questions

Answers built from our own checks of this server.

Why is there no uptime for facts402: x402 API finder + fact checks?

facts402: x402 API finder + fact checks 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 pypi package facts402-mcp was installed 631 times last week.

How do I connect facts402: x402 API finder + fact checks?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls facts402-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use facts402: x402 API finder + fact checks?

The pypi package facts402-mcp was installed 631 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is facts402: x402 API finder + fact checks open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
