# NetIntel DNS Lookup

> NetIntel DNS Lookup is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Resolves all DNS record types for a domain, parses SPF/DKIM/DMARC from TXT records, and compares A records across Google, Cloudflare, and Quad9 resolvers to check propagation consistency.

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-291d8ccb
```

Example prompt: Can you look up all the DNS records for stripe.com — I want to see the A, MX, and TXT records including SPF, DKIM, and DMARC, and check whether the A records are consistent across Google, Cloudflare, and Quad9 resolvers?

## When to prefer this

Use this endpoint when you need a comprehensive, all-in-one DNS lookup that also parses email security records (SPF/DKIM/DMARC) and checks propagation consistency across major public resolvers — ideal for diagnosing email deliverability issues, verifying DNS changes have propagated, or auditing a domain's full DNS configuration in a single call.

## Known failure modes

- Invalid or non-existent domain returns empty or error record set
- Domain with no TXT records returns empty SPF/DKIM/DMARC fields
- DNS timeout from one resolver causes partial propagation result
- Malformed domain string returns validation error
- NXDOMAIN for domain that does not exist

## How this service works

Resolves all DNS record types for a domain, parses SPF/DKIM/DMARC from TXT records, and compares A records across Google/Cloudflare/Quad9 resolvers for propagation consistency.

## Output

Returns a structured breakdown of all DNS record types for the queried domain, parsed security records (SPF, DKIM, DMARC extracted from TXT), and a propagation comparison showing whether A records are consistent across Google (8.8.8.8), Cloudflare (1.1.1.1), and Quad9 (9.9.9.9) resolvers.
