How this service works
Bulk domain name availability lookup via live WHOIS: check many domains across many TLDs in one call and get a per-domain available true/false. Useful for naming, brand screening, and squatting checks.
Output
A per-domain response indicating whether each submitted domain name is available (true) or taken (false), derived from live WHOIS data. The agent receives a structured list mapping each domain to its availability status in a single response.
Example use cases
Brand name domain screening
“I'm launching a startup called Nebula and want to know which domains are still up for grabs — can you check nebula.com, nebula.io, nebula.ai, nebula.co, and nebula.app for me?”
Anti-squatting availability audit
“I need to check whether any of our competitors or squatters have registered these variants of our brand domain: acmecorp.net, acmecorp.org, acmecorp.io, acmecorp.co, and acmecorp.biz — please check all of them.”
Product launch domain shortlist
“We're deciding between three product names — can you check availability for zestify.com, zestify.io, zestiapp.com, zestiapp.io, zestapp.com, and zestapp.io so we can pick whichever name still has a good domain free?”
Technical details
Endpoint
POSThttps://api.clawfetch.ai/domains/checkWhen to prefer
Choose this endpoint when you need to check availability for multiple domains in a single API call rather than querying one domain at a time. It is ideal for brand screening, startup naming workflows, or anti-squatting audits where you have a shortlist of candidate domains across various TLDs. Prefer this over single-domain WHOIS tools when efficiency matters and you want structured true/false results rather than raw WHOIS text.
Side effects
- Invalid domain format — malformed domain strings may return errors or be skipped
- WHOIS rate limiting — very large batches may trigger throttling on upstream WHOIS servers
- TLD not supported — exotic or new TLDs may lack WHOIS coverage and return inconclusive results
- Network timeouts — live WHOIS lookups may time out for slow-responding registries
- Payment failure — x402 micropayment not processed results in 402 rejection before lookup
