Every TLD permutation of a name, in one call.

Pass a domain name (without TLD). Get back every TLD where that name is registered. Useful for brand-coverage analysis and lookalike sweeps.

WHAT THIS API RETURNS

One pivot across every TLD.

The All TLDs API takes a domain (the API will normalize off the extension if present) and returns every TLD permutation of that name registered in the corpus. The query runs across legacy gTLDs, new gTLDs, and the major ccTLDs Deepinfo monitors.

Use this for brand-coverage analysis (which TLDs has your brand been registered on, both legitimately and not) and for lookalike sweeps (which TLDs has an attacker registered the brand keyword on).

Pair with the Daily Registered Domain Names feed to catch new TLD registrations of your brand keyword as they appear.

REQUEST

One endpoint, one required parameter.

Endpoint:

GET https://api.deepinfo.com/v1/discovery/all-tlds?domain={domain}

page	query	integer	No	Page number for paginated responses. Defaults to 1.
page_size	query	integer	No	Page size for paginated responses. Defaults to a sensible per-endpoint limit; see docs.
ordering	query	string	No	Field to sort by; prefix with `-` for descending order.
export	query	boolean	No	When true, returns the full result set as a downloadable export instead of paginated JSON.
export_format	query	enum	No	Format of the export when `export=true`. Typically `json` or `csv`.
