# AgentRXI Domain Lookup

> AgentRXI Domain Lookup is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-15).

Looks up domain availability, WHOIS/RDAP registration data, DNS records (A, AAAA, MX, NS, TXT), and HTTPS status for any domain name.

## Facts

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 agentrxi-domain-lookup-8ec1c85b
```

Example prompt: Can you look up everything about openai.com — whether it's available, who the registrar is, when it was created and when it expires, the nameservers, and all its DNS records including A, MX, and TXT?

## When to prefer this

Use this endpoint when you need a comprehensive, one-call snapshot of a domain's registration, DNS, and HTTPS status. It combines RDAP/WHOIS, DNS resolution, and HTTPS probing in a single pay-per-call request, making it ideal for agents that need domain intelligence without stitching together multiple separate DNS and WHOIS APIs.

## Known failure modes

- Invalid domain format returns an error
- Domain not found in RDAP/WHOIS may return partial results
- Newly registered domains may have incomplete RDAP data
- DNS propagation delays may cause stale or missing records
- Timeout if the upstream RDAP or DNS resolver is slow

## How this service works

Domain lookup: availability, registrar, created and expiry dates (RDAP/WHOIS), nameservers, A/AAAA/MX/NS/TXT records, and whether the site answers over HTTPS.

## Output

Returns domain availability status, RDAP/WHOIS data (registrar, creation date, expiry date), nameservers, DNS records (A, AAAA, MX, NS, TXT), and whether the domain responds over HTTPS.
