## 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 liangyi-domain-audit-api-text-metrics-7d0dee0b
```

Example prompt: Can you run a DNS and email deliverability audit on 'example.com' — I need to know if the SPF, DKIM, and DMARC records are properly set up?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call audit of a specific domain's public DNS and email-delivery records (MX, SPF, DKIM, DMARC) without setting up a full DNS monitoring subscription. It is well-suited for one-off checks, pre-launch validations, or automated workflows that verify email infrastructure on demand.

## Known failure modes

- Missing or empty 'text' parameter returns a validation error
- Domain does not exist or has no public DNS records, resulting in empty or null audit fields
- Network timeout when querying authoritative DNS servers for obscure TLDs
- Malformed domain input (e.g. URL instead of bare domain) may produce unexpected results
- Payment failure via x402 protocol prevents the call from completing

## How this service works

## Output

Returns a structured JSON object containing the results of a public DNS and email-delivery records audit for the provided text/domain input, likely including presence and validity of MX, SPF, DKIM, and DMARC records, along with any detected misconfigurations or missing entries.
