Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 bitbooth-whois-91e4e4f2 -d '<json body>'
```

Example prompt: Can you pull the full WHOIS record for stripe.com — I want to know the registrar, when it was created, when it expires, and what name servers it's using?

## When to prefer this

Choose this endpoint when you need structured, parsed WHOIS data including registrar, dates, and name servers for any domain name — especially when doing domain ownership audits, expiry monitoring, or pre-acquisition research. Prefer it over raw DNS lookups (use BitBooth DNS for that) when registration metadata rather than DNS records is the goal. The SSRF protection and IPv4/IPv6 input rejection make it safe to call with user-supplied domain inputs.

## Known failure modes

- IPv4 or IPv6 address inputs are rejected — only domain names are accepted
- Domain not found in WHOIS registry returns an error or empty record
- Per-connection 5-second timeout may result in partial or failed responses for slow registries
- SSRF-blocked DNS attempts for internal/private hostnames will fail
- Payment of 0.005 USDC required per call; insufficient funds will prevent execution
- Unsupported TLDs or newly created domains may return incomplete WHOIS data

## How this service works

BitBooth Whois: pay 0.005 USDC, get the parsed whois record for any domain — registrar, creation/updated/expiry dates, name servers, status flags, plus the raw whois text. Two-hop resolution via whois.iana.org then the authoritative registry over TCP port 43. 5s per-connection timeout cap. Rejects IPv4/IPv6 inputs and blocks SSRF at the DNS layer. Built for agents auditing domain ownership, monitoring expiry, or pre-flighting a target.

## Output

A structured JSON object containing the parsed WHOIS data for the queried domain: registrar name, creation date, last updated date, expiry date, name server list, status flags, plus the full raw WHOIS text as returned by the authoritative registry. Resolved via two-hop lookup through whois.iana.org and the relevant TLD registry over TCP port 43.
