Technical details
Endpoint
GEThttps://monitor.intel.rallylive.ca/watch/monitor/is-down/americanexpress-com?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need change-detection for americanexpress.com availability — not just a one-time status check. It is ideal for scheduled polling workflows where you want to be notified only when something changes, avoiding alert fatigue from repeated identical results. Prefer this over a generic HTTP ping when you need before/after diff context and a persistent 90-day history of results.
Side effects
- No previous check exists (first call returns current state only, changed=false or null)
- americanexpress.com itself is unreachable due to network issues unrelated to site status
- Cached result is stale beyond 90 days, clearing comparison baseline
- Payment of $0.02 USDC not processed, resulting in 402 response
- Transient check failure returns ambiguous down status
