Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/watch/email/hosted-by/mailbox-org?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to track changes in whether a domain's email is hosted by Mailbox.org over time, rather than just performing a one-time check. It is ideal for scheduled monitoring pipelines, alerting workflows, or competitive intelligence tasks where knowing when the status changed (and what exactly changed) matters more than just the current state.
Side effects
- Domain not previously checked — no baseline exists for comparison, 'changed' will be null or baseline will be set on first call
- DNS resolution failure via Cloudflare DoH — MX records unavailable, check returns error
- Invalid or non-existent domain — lookup fails with error response
- Payment failure — x402 payment not processed, request rejected
- Rate limiting or timeout — upstream DNS query takes too long
