# Domain Availability Checker — Multi-TLD Search

> Domain Availability Checker — Multi-TLD Search is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-11).

Checks whether a domain name is available, taken, or likely available across up to 20 TLDs simultaneously, returning registrar details and dates for taken domains.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-data-tools-revmesh2074-workers-dev-domain-availability-checker-32157560
```

Example prompt: Can you check if 'lunarpay' is available as a domain — look across .com, .io, .ai, .app, and .co, and tell me which ones are free and which are taken (with expiry dates if possible)?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
