How this service works
Check domain and handle availability for a startup name. Checks .com/.io/.ai/.co/.dev domains, Twitter, GitHub, npm, PyPI.
Output
Returns availability status for .com, .io, .ai, .co, and .dev domains, plus Twitter handle, GitHub username, npm package name, and PyPI package name — all keyed to the queried company name or keyword.
Example use cases
Quick brand availability check
“I'm launching a new product called 'Nexus' and I need to make sure I can actually use that name. Can you check if nexus.com, nexus.io, nexus.ai are available, and also let me know if @nexus is taken on Twitter and GitHub?”
Developer package name validation
“Before I publish my new framework 'Catalyst', can you verify it's not already taken? I need to know about the .dev and .co domains, plus whether catalyst is available as an npm package and on PyPI.”
Full startup identity verification
“We're thinking of naming our startup 'Prism' and want to secure our entire web presence at launch. Can you run a full check on all the major domains (.com, .io, .ai, .co, .dev), Twitter handle, GitHub org, npm, and PyPI to see what we can actually grab?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/startup-domain-checkWhen to prefer
Use this endpoint when you need a one-shot multi-platform availability check for a startup or product name, covering both domain registrars and developer/social handles simultaneously, rather than querying each registry separately.
Side effects
- Invalid or missing company_name parameter returns a 400-level error
- External registry timeouts may cause partial results for some platforms
- Rate limiting from downstream services (Twitter, GitHub, npm, PyPI) may reduce freshness
- Very long or special-character names may return unexpected results
