As of 2026-08-02, nonvisceral-eloisa-mousily.ngrok-free.dev/api/composite-signal on Base answered only 33.3% of 81 reliability checks over the past 30 days, leaving it unreliable for anything production-facing. Responses came back slow at 1592 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 $0.0600. Its x402-trust grade is D (score 49.0 from a solid sample, tracked for 32 days), so it warrants caution before relying on it.
Bundled market state inference API: combines BTC/ETH regime direction, liquidation cascade risk + open interest velocity, and composite crypto sentiment in a single call. Discounted vs $0.07 a-la-carte. Designed for trading agents that need a complete market snapshot per decision cycle.(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 (some 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
