As of 2026-09-14, agent402.tools/api/memory/log on Base responded to 93.8% of 32 reliability checks over the past 30 days, often enough to use but with outages frequent enough to plan around. Responses came back sluggish at 772 ms average from a single EU vantage point (so this includes network distance to the endpoint) and its advertised price moved 1 time (now $0.0010). Its x402-trust grade is C (score 55.0 from a moderate sample, tracked for 84 days), so it is best avoided for now.

Why this verdict?

The latest analysis recorded 2 error flags and 1 warning for this endpoint.

This page is a cached snapshot (computed 8 hours ago, refreshed at least every 24h): it tells you what the verdict is, not why. What each flag says, which wallet or network it concerns and the evidence behind it is the paid trust report, re-probed live at the moment you ask.

A wallet payment page opens first; approve the USDC payment and the full JSON report loads right in your browser. Agents use the x402_trust_score MCP tool or POST /v1/x402-trust directly. Want a taste first? Read a free full sample report.

Advertised descriptionTamper-evident history of every change to a namespace - an append-only, hash-chained audit log the server attests to (provenance an agent can't forge for itself). ?owner=0x… reads a granted namespace.(Provider-supplied: an unverified claim, not checked by us.

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.

↑ 10 better alternatives available

10 better-scored endpoints serving a semantically similar purpose exist.

We don't reveal which ones here. The ranked list (resource URLs, exact scores, prices & similarity, etc...) is one paid call away. Purchase it right here with a browser wallet, no code required:

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.
  • ✓
    Instant snapshot refresh:
    Every paid call also re-writes this cached snapshot, so the page, badge and card update immediately instead of waiting for the 24h cycle.
  • ✓
    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).
