As of 2026-08-15, jax.tail5e0766.ts.net:8443/api/v1/agent-commerce-listing-card on Base held a near-perfect 99.8% uptime across 417 reliability checks since first seen 2026-08-01 (14 days). Responses came back slow at 1657 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 $2.00. Its x402-trust grade is B (score 70.0 from a solid sample, tracked for 14 days), so it currently looks safe to use.
Download a checksum-pinned five-file commercial-use starter for turning verified facts about one existing seller-controlled paid HTTP product into one structured marketplace or directory listing. It includes one fillable Markdown card, a zero-dependency local structural checker, a narrow single-product commercial-use license, an integrity manifest, and a guide. It does not build, test, host, publish, or implement the product. The paid GET costs 2 USDC on Base and returns raw application/zip bytes with SHA-256 14922a96e3034aca50b3bb9c1549440f9c001d8ad91659cb7d651a26f5b7b264.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
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.
10 better-scored and cheaper 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:
A wallet payment page opens first; approve the USDC payment and the ranked JSON list loads right in your browser. Agents use the x402_find_alternatives MCP tool or POST /v1/similar directly.

- ✓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 (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
