X402 Trust Scores

Created By

x402-trust gives AI agents a "check before you pay" layer for the x402 ecosystem.

Overview

This MCP queries a service (https://x402.fuchss.app/) that continuously probes every publicly listed x402 endpoint and scores each one (0-100, graded A-F) from real signals:

30-day uptime
402-envelope spec compliance
latency
observed age
advertised-price stability
actual on-chain USDC settlement volume to the endpoint's payTo address

Every score is deterministic and auditable. Full component breakdown, machine-readable flags, and a clear verdict (proceed / caution / avoid), with a live probe at purchase time so "up" means up right now.

It catches what uptime-only checkers and raw explorers miss:

dead endpoints still showing cumulative transaction counts
settlement volume that can't be attributed to one endpoint because the payTo is shared
malformed resource URLs
recently-changed payTo addresses

Free tier:

ecosystem stats
a top-25 trustworthy-endpoint leaderboard
a preview example of the currently highest, lowest and average scored endpoints with all stats.

Paid (pay-per-call over x402, auto-pays if a Base USDC wallet is configured):

per-endpoint trust score
raw observation history

All endpoints are also listed on x402scan. Go to https://www.x402scan.com/ and search for "x402.fuchss.app".

Let your agent know before he pays.
