2s.io/api/earth/events
As of 2026-08-15, 2s.io/api/earth/events on Base responded to 90.3% of 31 reliability checks over the past 30 days, often enough to use but with outages frequent enough to plan around. Responses came back moderate at 494 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 $0.0030. Its x402-trust grade is A (score 81.9 from a moderate sample, tracked for 64 days), so it currently looks safe to use.
Global natural events tracker via NASA EONET v3 (Earth Observatory Natural Event Tracker). Returns active and historical events curated by NASA EOSDIS: wildfires, severe storms, volcanoes, floods, droughts, landslides, sea/lake ice, dust/haze, manmade incidents, water-color anomalies. Each event includes geo-located observation points with timestamps, source attribution (USGS, NWS, IRWIN, GDACS, etc.), and category. Filter by status (open/closed/all), days-back window, category, or bounding box.(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.
A better-scored endpoint serving a semantically similar purpose exists.
We don't reveal which one 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
