FreeTLD Intelligence API

Get TLD

GET/tlds/{tld}No key

One TLD in full: registry facts, phases, market, quality band and registrar prices.

A public-set TLD with its figures computed carries the website insight bundle without its name sample, news, description words and topics. Any other TLD answers its registry facts and phases, and its market on a paid subscription. A removed or terminated TLD is 404.

AccessNo key. Limited per address; a key adds the paid fields.

BillingOne call.
