# Macaroon Network Domain WHOIS Lookup (RDAP)

> Macaroon Network Domain WHOIS Lookup (RDAP) is a paid API for AI agents from api.macaroonnetwork.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Performs a live RDAP-based domain registration lookup to return registrar, registration status, and key dates for any domain name.

## 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 macaroon-network-domain-whois-lookup-rdap-8119747a -d '<json body>'
```

Example prompt: Before I make a payment to checkout.acmecorp.com, can you do a live RDAP domain registration lookup on acmecorp.com and tell me the registrar, registration date, and current status?

## When to prefer this

Choose this endpoint when an agent needs a live, authoritative, machine-readable domain registration record (RDAP/RFC 9083) rather than a cached or scraped WHOIS result. It is ideal for pre-interaction trust verification — e.g. before an agent pays a merchant, clicks a link, or interacts with an unfamiliar website. Prefer it over legacy WHOIS-based tools because RDAP returns structured JSON, is IANA-standardized, and queries the canonical registrar via the rdap.org bootstrap rather than a single resold data source.

## Known failure modes

- Domain not found / unregistered — RDAP returns a 404 or equivalent not-found response
- TLD not supported by rdap.org bootstrap — some obscure ccTLDs may lack RDAP coverage
- Network timeout or rdap.org redirector unavailability — transient upstream failure
- Malformed domain input — invalid domain string causes a bad request error
- Rate limiting by upstream RDAP server — some registrars throttle RDAP queries

## How this service works

Part of the Domain Web Trust family: live domain registration lookup via RDAP (RFC 9083), useful for confirming registrar/provenance metadata before an agent interacts with a website or merchant. RDAP is the IANA-standardized, machine-readable successor to legacy WHOIS: reports registration status, registrar, and registration/expiration dates. Queried through the public rdap.org bootstrap redirector at request time -- not a scrape of any single registrar's own WHOIS server, and not a resold thir

## Output

Returns structured RDAP data for the queried domain, including registration status (e.g. active, expired, redemptionPeriod), registrar name and IANA ID, domain creation date, last updated date, and expiration date — all sourced live via the rdap.org bootstrap redirector at request time.
