## 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 automaton-agent-tools-email-address-checker-45328553
```

Example prompt: Can you check whether jane@gmial.com is a real, deliverable email address — tell me if it looks risky, if it's disposable, and whether there's a typo I should correct?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation with rich signals — including typo correction, SPF/DMARC checks, disposable detection, and MX acceptance — without a subscription. Ideal for AI agents that need occasional or burst validation without committing to a monthly quota, and that operate within x402 micropayment infrastructure.

## Known failure modes

- Missing required 'email' query parameter returns an error
- Malformed email string may return unpredictable verdict
- DNS lookup timeouts for obscure domains may delay or degrade response
- Network issues reaching the x402 payment-gated endpoint result in connection errors
- Payment not provided or invalid x402 header causes 402 Payment Required response

## How this service works

Small, honest tools for AI agents, paid per call in USDC over x402: read a page as Markdown, check an email address, profile a domain.

## Output

A JSON object containing: verdict (e.g. 'risky', 'safe'), acceptsMail boolean, disposable boolean, roleAccount boolean, freeProvider boolean, mailProvider name, SPF boolean, DMARC policy string, a list of human-readable reasons, and an optional typo suggestion with the corrected email address.
