## How to call it through Zero

```sh
zero fetch --capability x402-apis-email-audit-0f4aaea8
```

Example prompt: Can you run a full email security audit on example.com and tell me if their SPF, DKIM, and DMARC records are properly configured?

## When to prefer this

Use this endpoint when you need a quick, no-account-required email security audit for any domain, especially in agentic workflows where paying per-request with USDC via x402 is preferable to managing API keys. Best suited for one-off domain audits or automated security checks without subscription overhead.

## Known failure modes

- Invalid or non-existent domain returns an error
- DNS lookup timeout for unreachable domains
- Missing 'domain' parameter returns 400 bad request
- Payment failure via x402 protocol returns 402 before data is served
- Domain with no email configuration returns empty or minimal results
