Frequently Asked Questions

How accurate is the domain availability check?

We use RDAP (Registration Data Access Protocol) which queries authoritative domain registries directly. This provides the most accurate and up-to-date availability information possible.

Which TLDs can I check?

DomScan supports over 1000 TLDs including all popular extensions like .com, .net, .org, .io, .co, .dev, and many country-code TLDs. Use our /v1/coverage endpoint to see the full list.

Is there a rate limit?

The free plan includes generous rate limits. Cached results have no limit. Fresh RDAP lookups are throttled to protect upstream registries. Use prefer_cache=1 for best performance.

Can I check multiple domains at once?

Yes! Use the /v1/status/bulk endpoint to check multiple complete domain names in a single API request. Perfect for domain search tools.
