As of 2026-08-15, x402.donnyautomation.com/treasury on Base responded to 92.5% of 147 reliability checks since first seen 2026-08-03 (11 days), often enough to use but with outages frequent enough to plan around. Responses came back moderate at 496 ms average from a single EU vantage point (so this includes network distance to the endpoint) and its advertised price moved 1 time (now $0.0300). Its x402-trust grade is B (score 70.5 from a solid sample, tracked for 11 days), so it currently looks safe to use.
US Treasury par yield curve API - every constant-maturity rate from 1 month to 30 years for any published business day, plus the spreads nobody wants to compute themselves. 2s10s, 3m10y and 5s30s are returned with an explicit inversion flag, because the real question is whether the curve is inverted, not what fourteen numbers are. A tenor Treasury did not publish that day is null, never zero. For macro, rates, credit and risk agents.(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
