## 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 basalt-domain-check-6d9a3b32 -d '<json body>'
```

Example prompt: Can you check whether 'acmestartup.io' is currently registered or still available to buy, and if it's taken, tell me when it expires and who the registrar is?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) programmatic lookup of domain registration status and WHOIS-style metadata for a single domain, particularly in agentic workflows that pay per use via x402 on Base. Prefer over manual WHOIS queries or heavier domain registrar APIs when you only need status, availability, creation, expiry, and registrar — not full DNS records or bulk lookups.

## Known failure modes

- Invalid or malformed domain string returns an error
- Unknown TLDs or very new domains may return incomplete WHOIS data
- Rate limiting may apply under heavy usage
- Render cold-start latency may cause timeouts on first call after inactivity
