# DNS TXT Record Lookup (x402atlas)

> DNS TXT Record Lookup (x402atlas) is a paid API for AI agents from dns.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Resolves DNS TXT records for a hostname, returning SPF, DKIM, DMARC, and domain-verification strings as clean JSON.

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 dns-txt-record-lookup-x402atlas-b9d80699
```

Example prompt: Can you pull all the DNS TXT records for example.com so I can check whether SPF, DKIM, and DMARC are configured correctly?

## When to prefer this

Use this endpoint when you need to inspect or validate DNS TXT records for email authentication (SPF, DKIM, DMARC) or domain ownership verification. Prefer it over a general DNS resolver when you specifically need TXT records returned as structured JSON ready for agent consumption, and want per-query micropayment billing instead of a subscription.

## Known failure modes

- Domain does not exist — returns empty TXT record list or DNS NXDOMAIN error
- No TXT records configured for the hostname — returns empty array
- Invalid hostname format — returns validation error
- DNS resolution timeout — returns timeout or upstream error
- Rate limiting or payment failure — returns 402 or 429 status

## How this service works

DNS TXT record lookup — a domain's TXT records as a clean JSON list: SPF, DKIM and DMARC policy strings plus site-verification and domain-ownership tokens, for email-authentication and domain-verification checks.

## Output

A clean JSON object containing all DNS TXT records associated with the queried hostname, including SPF policy strings, DKIM public key records, DMARC policy entries, and any domain-ownership verification tokens.
