## 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 tanod-dnspeek-domain-availability-ff10cad6 -d '<json body>'
```

Example prompt: Can you check if 'mycoolstartup.io' and 'mycoolstartup.com' are available to register?

## When to prefer this

Use this endpoint when you need a quick, no-signup programmatic check of domain availability using authoritative RDAP data and DNS fallback, especially for bulk checks of up to 50 names at once or for internationalized (Unicode/IDN) domain names. It is pay-per-call with no subscription required, making it ideal for agent workflows that only occasionally need domain lookups. Prefer a registrar API if you need guaranteed accuracy for premium/reserved names or need to initiate a purchase.

## Known failure modes

- 422 if any domain name in the batch is invalid (whole call rejected, not charged)
- RDAP server unavailable for some TLDs leading to ambiguous 'unknown' status
- Premium, reserved, or blocked names may appear available
- Name sniping risk: domain may be taken between check and registration
- Unicode names normalized to xn-- punycode form may differ from user intent

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object with per-domain results including status ('available', 'registered', or unknown), a human-readable note, evidence showing RDAP HTTP status and whether NS records were found, plus aggregate counts of available/registered/unknown names and a disclaimer noting that registrar confirmation is needed before purchase.
