# Earliest Expiry First The domains on Cloudflare Email Routing, the earliest WHOIS expiry date first (ordering=domain.whois.expiry_date). Source: https://docs.deepinfo.com/reference/discovery/reverse-mx/examples/ordering-expiry-date/ Last updated: 2026-09-24 --- `GET https://api.deepinfo.com/v1/discovery/reverse-mx?ordering=domain.whois.expiry_date&mx=route1.mx.cloudflare.net&page_size=25` The domains on Cloudflare Email Routing, the earliest WHOIS expiry date first (`ordering=domain.whois.expiry_date`). Example 1 of 1 in **Ordering** · [Reverse MX Examples](/reference/discovery/reverse-mx/examples/) · endpoint: [Reverse MX](/reference/discovery/reverse-mx/) Tags: `param` `ordering` · `param` `mx` · `value` `domain.whois.expiry_date` · `value` `route1.mx.cloudflare.net` `ordering=domain.whois.expiry_date` sorts by the expiry date in the WHOIS record, earliest first. The first records have expiry dates long in the past (`pub.pw` on August 26, 2016, `vb.lk` and `byte.lk` in 2018): their WHOIS record shows an expiry date that has passed, while their MX record still points to Cloudflare. Sorting on a date field is a quick way to find such stale records. In the response, look at `results[].domain.whois.expiry_date`. ## Request | Parameter | In | Value | |---|---|---| | `ordering` | query | `domain.whois.expiry_date` | | `mx` | query | `route1.mx.cloudflare.net` | | `page_size` | query | `25` | ```bash curl 'https://api.deepinfo.com/v1/discovery/reverse-mx?ordering=domain.whois.expiry_date&mx=route1.mx.cloudflare.net&page_size=25' \
