Use this when

When does this domain expire?
How many days are left before this domain expires?
You are monitoring a domain portfolio for renewals.
You need to know whether a domain has lapsed or entered redemption or pending delete.
You need expiry plus registrar in one cheap call.

Don't use this when

You also need nameservers, DNSSEC, the creation date or the registrar's abuse contact - use domain.registration.
You need registrant contact details - registries redact them.
You need an authoritative availability or drop-catch signal - use a registrar EPP check.
The TLD has no RDAP service in the IANA bootstrap (returns UNSUPPORTED_REGION).

If the user has asked you to inspect a specific website, page or URL, use your browsing tool instead — this capability only returns the RDAP record.
