# NetIntel WHOIS/RDAP Domain Lookup

> NetIntel WHOIS/RDAP Domain Lookup is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Looks up domain registration metadata via RDAP, returning registrar info, creation/expiry dates, nameservers, status flags, and a trustworthiness/availability score.

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 netintel-production-440c-up-railway-app-d0d087df
```

Example prompt: Can you look up the RDAP registration details for stripe.com — I want to know who the registrar is, when it was created, when it expires, and whether it has any abuse flags or trustworthiness concerns?

## When to prefer this

Use this endpoint when you need structured, machine-readable domain registration metadata (registrar, dates, nameservers, status) with a pre-computed trustworthiness/availability score and abuse flag detection. Prefer over raw WHOIS when you want normalized output with an actionability grade rather than free-text WHOIS responses.

## Known failure modes

- Domain not found in RDAP registry — returns error or empty result
- Invalid domain format supplied — validation error
- TLD not supported by any known RDAP bootstrap server — lookup fails
- RDAP registry temporarily unavailable — timeout or upstream error
- Payment not included or insufficient — 402 Payment Required

## How this service works

Look up domain registration metadata via RDAP — returns registrar, creation/expiry dates, nameservers, status flags, and an actionability score so agents can assess domain trustworthiness or availability risk.

## Output

Returns a structured object with the domain's TLD, registrar name, IANA registrar ID, creation/updated/expiry timestamps, days until expiry, nameservers list, status flags array, whether abuse flags are present, an actionability score (numeric), a letter grade, a findings array with notable observations, and the raw RDAP URL used for the lookup.
