As of 2026-08-16, agentdata-api.sander-van-aard.workers.dev/crypto/feed on Base held a flawless 100.0% uptime across 256 reliability checks since first seen 2026-07-29 (18 days). Responses came back sluggish at 502 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 75.8 from a solid sample, tracked for 18 days), so it currently looks safe to use.
Subscribe for 30 days to the change feed behind /crypto/scan: one cursor over the upstream advice ledger, all coins at once. Returns a handle and a cursor; polling is then free and unlimited: /crypto/feed/since returns every published change since your cursor — new signals, classification flips, status changes (PUBLISHED/STALE/INVALIDATED), score and entry-zone changes. Be first to know when the market state flips; the full advice per signal stays a separate paid call.(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
