proceed grade B x402 endpoint Base found on CDP Bazaar delisted confidence 1.00
https://api-production-54bd.up.railway.app/v1/price

As of 2026-08-15, api-production-54bd.up.railway.app/v1/price on Base held 98.7% uptime across 550 reliability checks over the past 30 days, with only occasional misses. Responses came back sluggish at 944 ms average from a single EU vantage point (so this includes network distance to the endpoint) and it has held its advertised price steady at $0.0010. Its x402-trust grade is B (score 69.4 from a solid sample, tracked for 42 days), so it currently looks safe to use. It is no longer listed in the x402 directory.

Cached snapshot, computed 71 hours ago. This is the full-density trust score computed from every probe, same as the paid API... but it may be up to 24 hours old. For a guaranteed-current answer it re-probes the endpoint live at the moment you ask, adds a confidence band, the full component breakdown, structured risk flags and on-chain settlement proof:
Browser wallet payment, no code required. Agents use POST /v1/x402-trust or the x402_trust_score MCP tool.

Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint; a geographically distant endpoint reads slower even when its server is fast, so it is only lightly weighted in the score.

This is the free cached snapshot. Here's what the paid API adds.
  • ✓
    Live probe at decision time:
    We re-check the endpoint the moment you ask (timestamped) and compute the score from all scores up until this moment, instead of this cached snapshot that may be up to 24h old.
  • ✓
    Confidence band, full component breakdown & structured risk flags:
    Exactly why the score is what it is, machine-readable.
  • ✓
    On-chain settlement proof:
    Real USDC volume & distinct-payer count for the payTo wallet: is anyone actually paying it?
  • ✓
    90-day raw history:
    Every listing/price/payTo change and probe result (via POST /v1/x402-history), up to 90 days back.
  • ✓
    The ranked better-scored alternatives:
    The resource URLs, scores & prices we don't reveal above (via POST /v1/similar), if there are better alternatives available.
  • ✓
    Change & liveness alerts:
    Get notified on payTo/price changes, spec regressions or downtime (via POST /v1/watch-endpoint-30d). Connect up to 10 Discord / Slack webhooks or poll regularly with bearer auth. Increases probe-density to every 5 minutes instead of the usual 30 for the watched endpoint.

... Simply give your agents the tools to do all of that for you, with a simple command
$npx -y x402-trust-mcp

Prefer HTTP? Call POST /v1/x402-trust directly (pay-per-call over x402, from $0.005).
