# Foundry Domain WHOIS via RDAP

> Foundry Domain WHOIS via RDAP is a paid API for AI agents from minty-sprout.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).

Looks up domain registration details (registrar, creation/expiry dates, status flags, and nameservers) using RDAP for a given domain name.

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 foundry-domain-whois-via-rdap-08904840 -d '<json body>'
```

Example prompt: Can you look up the WHOIS registration details for shopify.com — I want to know the registrar, when it was created, when it expires, its current status, and which nameservers it's using?

## When to prefer this

Use this endpoint when you need structured, machine-readable WHOIS/RDAP data for a domain, especially registrar identity, lifecycle dates, and nameservers. Prefer it over raw DNS lookups when you need registration metadata rather than DNS records, and over scraping traditional WHOIS when you need clean JSON output. It complements the sibling DNS lookup endpoint for a full picture of a domain's configuration.

## Known failure modes

- Domain not found in RDAP — returns empty or error response for unregistered or TLDs without RDAP support
- Invalid domain input — malformed strings may return a validation error
- RDAP registry timeout — upstream RDAP server may be slow or unresponsive for certain TLDs
- Rate limiting — repeated rapid calls may be throttled by upstream RDAP servers
- Payment failure — the $0.001 USDC x402 micropayment must succeed before the query is executed
