Overview

SOLx402 is an MIT-licensed, open-source MCP server that lets agents such as Claude or Cursor discover x402-enabled services from a facilitator, pay for them in USDC on Solana, and check wallet balances. It's listed on Smithery with setup guides for Cursor, VS Code, and Claude, and flags a 60-second minimum timeout to account for Solana confirmation delays.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

State changed on 2026-09-01 (unclear → failing), 2026-09-27 (failing → responding).

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 40 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. The rate above leaves those checks out; the counts include them.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
