As of 2026-09-14, markt.halowerk.com/orderbook/imbalance on Base responded to 87.5% of 600 reliability checks over the past 30 days, often enough to use but with outages frequent enough to plan around. Responses came back moderate at 483 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 $0.0030. Its x402-trust grade is B (score 77.5 from a solid sample, tracked for 36 days), so it currently looks safe to use. It is no longer listed in the x402 directory.

This page is a cached snapshot (computed 54 hours ago): 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.

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.

- ✓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 (viaPOST /v1/x402-history), up to 90 days back. - ✓The ranked better-scored alternatives:
The resource URLs, scores & prices we don't reveal above (viaPOST /v1/similar), if there are better alternatives available. - ✓Change & liveness alerts:
Get notified on payTo/price changes, spec regressions or downtime (viaPOST /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.
