## 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 the-stall-domain-availability-checker-12ffced2
```

Example prompt: Can you check if 'luminara' is available to register across .com, .io, .ai, and .app?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
