domain

Lookup subdomains for domain.

Returns an array of subdomains.

The response contains the subdomains only, the domain not included (eg.: ["one", "two", ...]).

If a FQDN is requested than the domain name will be taken out and used in the lookup (eg.: /api/lookup/columbus.elmasy.com will be the same as /api/lookup/elmasy.com)

If Accept header is set to text/plain, this endpoint returns a newline delimetered text of the list (eg.: one\ntwo\nthree).

Note

  • The subdomain part will be trimmed (eg.: /api/lookup/totally.invalid.elmasy.com will be the same as /api/lookup/elmasy.com).
  • If domain not found, the server saves for later process.
  • Only the subdomains are sent in the response to save CPU and RAM on the server side and save bandwith on both client- and server-side.
