## 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 api-strale-io-33286503
```

Example prompt: Can you do a full DNS lookup for github.com and tell me all its record types including A, MX, NS, TXT, and whether SPF and DMARC are properly configured?

## When to prefer this

Use this endpoint when you need a comprehensive, single-call DNS audit covering all major record types plus email security records (SPF/DMARC) simultaneously, rather than making multiple separate DNS queries. Ideal for domain infrastructure investigation, email deliverability troubleshooting, or security audits.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns empty or error response
- Invalid domain format provided — validation error
- DNS timeout or upstream resolver failure — service error
- Domain has no records of a specific type — returns empty array for that record type
