How this service works
Four-region consensus check of a URL
Output
A consensus result from four geographic regions indicating whether the URL is reachable and consistent, including per-region probe outcomes and an overall availability verdict.
Example use cases
Global site outage diagnosis
“My users in different countries are saying my site is down — can you do a consensus check on https://mystore.example.com to see if it's actually unreachable from multiple regions?”
Pre-launch API endpoint validation
“Before we go live, can you probe https://api.newproduct.io/v1/status from multiple regions to confirm it's consistently accessible everywhere?”
Third-party dependency availability check
“We depend on https://payments.thirdparty.com/ping — can you run a multi-region check to verify it's up and responding consistently right now?”
Technical details
Endpoint
GEThttps://sentinel.rootstuff.io/x402/checkWhen to prefer
Choose this endpoint when you need a geographically distributed, multi-region view of URL availability rather than a single-point ping. It is ideal for diagnosing whether a site is down globally versus locally, validating public endpoints before launch, or checking third-party dependency health from a consensus perspective.
Side effects
- Private or reserved IP addresses are refused with an error
- Malformed or non-HTTP/HTTPS URLs are rejected
- Target host may time out in one or more regions, affecting consensus
- URL may be reachable in some regions but not others, resulting in split consensus
- Rate limiting or payment failure may block the request
