# Agent Tools Domain Lookup

> Agent Tools Domain Lookup is a paid API for AI agents from agents.crowdspark.me, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Returns comprehensive domain intelligence in one call: WHOIS/RDAP registration data, DNS records (A/AAAA/MX/NS/TXT), SPF, DMARC, and HTTPS reachability for any domain.

## 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 agent-tools-domain-lookup-de911107
```

Example prompt: Can you look up everything you can find on crowdspark.me — who registered it, when it expires, what DNS records it has, whether it's reachable over HTTPS, and whether it has SPF and DMARC set up?

## When to prefer this

Use this endpoint when you need a comprehensive, all-in-one domain intelligence snapshot — combining WHOIS registration data, full DNS record resolution, email security posture (SPF/DMARC), and HTTPS reachability in a single API call. Prefer it over individual DNS or WHOIS tools when you need correlated data for due diligence, phishing investigation, or lead research workflows where making multiple separate API calls would be inefficient.

## Known failure modes

- Domain not found or not registered — returns registered: false with empty DNS records
- Invalid domain format — returns a 400-level error
- RDAP/WHOIS data unavailable for some TLDs — registration fields may be null
- DNS resolution timeout — individual record types may be missing
- Rate limiting — 429 response if too many requests are made in a short period

## Output

A JSON object containing: domain registration status, registrar name, creation and expiry timestamps (from RDAP/WHOIS), DNS records (A, AAAA, MX, NS), email security records (SPF string, DMARC value), and HTTPS reachability status with HTTP status code — all in a single response.
