## 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-the402-ai-2a2f3973 -d '<json body>'

Example prompt: Can you run a full DNS and domain health audit on example.com and tell me if there are any misconfigurations, missing records, or issues I should fix?

## When to prefer this

Use this endpoint when you need a comprehensive DNS health check and domain audit rather than just checking domain availability. Ideal for diagnosing DNS misconfigurations, verifying DNS record completeness (A, MX, TXT, CNAME, NS), or getting a health score for a domain before launch or after incidents.

## Known failure modes

- Invalid or non-existent domain name provided — returns error or empty results
- Domain is unreachable or DNS resolution fails — may return partial results
- Payment failure via x402 protocol — endpoint returns 402 and audit is not performed
- Timeout if DNS servers are slow to respond — may return partial audit data
