scvd.store/api/buy/spot_check
As of 2026-09-14, scvd.store/api/buy/spot_check on Base responded to 93.4% of 183 reliability checks since first seen 2026-08-27 (18 days), often enough to use but with outages frequent enough to plan around. Responses came back sluggish at 729 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 74.6 from a solid sample, tracked for 18 days), so it currently looks safe to use.
The latest analysis recorded 2 warnings for this endpoint.
This page is a cached snapshot (computed 10 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.
Spot Check. Name a host and get what this observatory already holds on it, signed: corpus rounds and verdicts as recorded, when we last actually knocked, our coverage of the window since we met it, and the gaps with their reasons. Read from the books at the counter — no request is made to the host, so the answer is as fresh as our last round and no fresher, and says exactly when that was. A host we have never observed returns not_observed, which is an answer about our books,…(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
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.
... Simply give your agents the tools to do all of that for you, with a simple command
npx -y x402-trust-mcpPrefer HTTP? Call POST /v1/x402-trust directly (pay-per-call over x402, from $0.005).
