## 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 agent402-tools-email-security-bundle-245fc9aa -d '<json body>'
```

Example prompt: Can you run a full email security audit on stripe.com — check SPF, DMARC, DKIM, and give me an overall deliverability score in one shot?

## When to prefer this

Choose this endpoint when you need a comprehensive email authentication audit in a single call rather than querying SPF, DMARC, and DKIM separately. Ideal for agents that need a quick composite deliverability verdict without orchestrating multiple tool calls. Best when you want a single x402 payment to cover all four underlying checks atomically.

## Known failure modes

- Domain not found or invalid — DNS lookup failure
- Domain has no SPF, DMARC, or DKIM records configured — partial results returned
- Malformed domain input — validation error
- Payment failure via x402 — request not processed
- Timeout on DNS resolution for one or more sub-checks

## How this service works

Bundled execution of the Email security workflow - Full email auth posture: SPF, DMARC, DKIM, and composite deliverability score in one call. One x402 payment runs 4 underlying tools (spf-check, dmarc-check, dkim-lookup, email-deliverability); partial-success per step.

## Output

A bundled response containing SPF record validity, DMARC policy details, DKIM lookup results, and a composite email deliverability score — effectively the full email authentication posture for the queried domain in a single API response.
