Use this endpoint when you need to discover competitor or similar-named domains for a given domain, especially in lead-generation, competitive intelligence, or brand research workflows. Prefer this over manual search when you want a programmatic, fast list of name-similar domains without needing full web scraping or WHOIS lookups.
Side effects
- Invalid or malformed domain name returns an error
- Domain not found or no similar domains available returns empty results
- Rate limiting or payment failure returns 402 or 429 status
- Network timeout if upstream lookup takes too long
