How this service works
Domain availability, domain name. Is a domain name free? Check one name across up to 20 TLDs at once (default com, net, org, io, ai, co, app, dev, xyz, me): available, taken (with registrar, creation and expiry dates) or likely available, from each registry's RDAP server, with DNS where a TLD has no RDAP. Use to pick a product or company name, or to check a brand before launch. Availability is not a price quote: premium and reserved names exist.
Output
Returns an object with the queried name, an array of per-TLD results (each with domain, lookup method, availability status, registrar, creation date, expiry date), and a flat list of available domain strings for quick reference.
Example use cases
Startup brand name validation
“I'm thinking of naming my startup 'Driftly' — can you check if driftly is available across .com, .net, .io, .ai, and .app, and tell me which are free?”
Pre-launch brand domain audit
“Before I launch my product under the name 'Vaultra', check domain availability across all the major TLDs — com, net, org, io, ai, co, app, dev, xyz, and me — so I know what's still up for grabs.”
Finding a free .ai or .dev domain
“Can you search for available domains for the name 'promptly' and focus on .ai and .dev TLDs? I want to know if either is free and, if taken, who owns them and when they expire.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/domain/availability?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, authoritative domain availability data from RDAP registries across multiple TLDs in a single call. It is preferable to a WHOIS scraper or registrar website when you need structured JSON output, batch TLD checking, and registrar/expiry metadata for taken domains — especially in automated agent workflows where you need to compare many TLD options at once without manual lookups.
Side effects
- TLD has no RDAP server and DNS lookup is inconclusive — status returned as 'likely available' rather than confirmed
- Registry timeout or rate-limit — partial results returned for some TLDs
- Invalid or malformed name input — may return an error or empty results
- Premium or reserved names reported as 'available' by RDAP but not purchasable at standard pricing — endpoint explicitly notes this limitation
- Internationalized or exotic TLDs may lack RDAP support and fall back to DNS-only checks
