Bulk availability checking across multiple TLDs. Takes a name fragment and returns comprehensive availability data across your chosen extensions.

generate_domain_variations

Intelligent alternative generation when your first choice is unavailable. Creates pronounceable variations using prefixes, suffixes, and semantic modifications—not random letter combinations.

Definitive yes/no availability verification for any list of domains. Accepts arrays, CSVs, or individual domain queries with authoritative registry validation.
