How this service works
Check domain name availability across multiple TLDs (com, net, org, io, ai, co, app, dev by default). Returns per-TLD availability status, registrar, and expiry for registered domains. Uses RDAP — authoritative registry data, no API key. Ideal for brand research, startup naming, and domain portfolio work.
Output
A map of TLD variants (e.g. luminara.com, luminara.io) each marked as available or taken, allowing the user to see at a glance which extensions they can register.
Example use cases
Example prompt
“Can you check if 'luminara' is available to register across .com, .io, .ai, and .app?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/domain-availability?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check domain name availability across multiple TLDs in a single call without needing an account or API key — ideal for startup naming workflows, brand research, or quick availability sweeps paid per-use via USDC on Base.
Side effects
- Invalid or empty domain name returns an error
- Too many TLDs requested (max 10) triggers validation failure
- Network or upstream WHOIS lookup timeout
- Non-string or malformed TLD values rejected
- Payment failure via x402 results in 402 response before any data is returned
