Frequently Asked Questions

What does the company lookup API do?

It checks whether the domain names matching your company name are available across selected TLDs.

Is this the same as the domain availability API?

Yes — it uses the same /v1/status endpoint, optimized here for company name checks.

Do I need an API key?

Yes, sign up for free to get your API key and 10,000 monthly credits.

Can I check multiple names at once?

Yes. Use /v1/status/bulk with a list of domains to check many names at once.
