X402 Paid Checks — questions

Answers built from our own checks of this server.

Why is there no uptime for X402 Paid Checks?
X402 Paid 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 npm package x402-paid-checks-mcp.
How do I connect X402 Paid 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 x402-paid-checks-mcp straight from npm; nothing to host, nothing to sign up for.
