## 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 mekong-trade-intel-email-verifier-0cbdd810 -d '<json body>'
```

Example prompt: Can you verify whether john.doe@example.com is a real, deliverable email address — check the syntax, DNS MX records, and whether it's a disposable address?

## When to prefer this

Choose this endpoint when you need a lightweight, no-account-required email validation that combines three checks (syntax, DNS MX, disposable detection) in a single call for $0.001 USDC. Ideal for agents that need to validate individual emails on-the-fly without managing API keys or subscriptions. Prefer this over full SMTP handshake validators when speed matters and you don't need inbox-level confirmation.

## Known failure modes

- Invalid or missing email query parameter returns an error response
- DNS lookup timeout if the email domain's nameservers are slow or unresponsive
- False negatives on newly created disposable domains not yet in the blocklist
- Payment failure or insufficient USDC balance prevents the call from completing
- Malformed email strings may return syntax-fail without attempting DNS lookup

## How this service works

Email verification API: syntax check + DNS MX record lookup + disposable email detection. Validate email lists, catch bounces. $0.001/call, USDC on Base. No account or API key needed.

## Output

Returns whether the email passes syntax validation, whether the domain has valid MX DNS records (meaning it can receive mail), and whether the address is from a known disposable/throwaway email provider — together forming a deliverability verdict.
