## How to call it through Zero

```sh
zero fetch --capability domain-whois-rdap-lookup-88c2decc
```

Example prompt: Can you look up the WHOIS and RDAP registration details for openai.com — I want to know who the registrar is, when it expires, and what nameservers it's using?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call WHOIS/RDAP lookups without signing up for an account or managing API keys. Ideal for AI agents that need on-demand domain intelligence as part of a broader workflow, especially when operating in a crypto-native or x402-payment environment. Prefer over traditional WHOIS APIs when zero-friction, anonymous, micropayment-based access is required.

## Known failure modes

- Domain not found or unregistered — may return empty or error response
- TLD not supported by RDAP — some ccTLDs lack RDAP coverage
- Redacted registrant info — GDPR-compliant registrars mask contact details
- Payment failure via x402 — call blocked if USDC payment is not settled
- Malformed domain input — invalid domain strings return error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object containing RDAP/WHOIS data for the queried domain: registrar name, registrant contact info (if available), registration and expiration dates, domain status flags, nameservers, and any associated RDAP links or events.
