As of 2026-09-14, agent402.tools/api/skill/api-investigation on Base held 97.1% uptime across 34 reliability checks over the past 30 days, with only occasional misses. Responses came back sluggish at 1075 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 $0.0170. Its x402-trust grade is A (score 84.2 from a moderate sample, tracked for 83 days), so it currently looks safe to use.

Why this verdict?

The latest analysis recorded 2 warnings 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 descriptionBundled execution of the API investigation workflow - Point at an unknown API endpoint and figure out how to use it: auth scheme, content type, version, rate limits, OpenAPI/Swagger spec discovery, and JSON response structure. The deterministic recon workflow before writing a single line of integration code. One x402 payment runs 7 underlying tools (url-parse, http-check, http-headers, extract, html-links, json-format, json-query); partial-success per step.(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.

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).
