Domains

List all domains available for creating short links. This includes default, premium, subdomain, and custom domains.

Domain Types

Type	Example	Access
default	u2l.ai	All plans
premium	u2.pe	Pro+ only
subdomain	myname.u2l.ai	Owner only
custom	links.mysite.com	Owner only (must be verified)

Subdomains and custom domains must be set up via the dashboard first. The API does not support adding or verifying new domains — only using existing ones when creating links.
