## 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 email-verification-api-api-production-17e1-9412f704
```

Example prompt: Can you verify whether john.doe@example.com is a real, deliverable email address — check if the domain actually accepts mail, whether it's a disposable address, and if it's a role account like info@ or support@?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call email validation with no signup or API key — ideal for one-off contact qualification, pre-send list hygiene, or when building an agent pipeline that needs to screen email addresses for deliverability, disposable providers, and role-account risk before outreach.

## Known failure modes

- Invalid or malformed email address input returns syntax error or undeliverable status
- Domain has no MX records — classified as undeliverable
- Payment not received or insufficient USDC — request rejected with 402
- Network timeout when querying MX records for the domain
- Unknown or newly registered domain may produce uncertain results

## How this service works

Email verification for AI agents — checks syntax, whether the domain accepts mail (MX), and flags disposable and role addresses, returning deliverable/risky/undeliverable. Pay-per-call in USDC via x402 — no signup, no API key. Use to clean lists and qualify contacts before sending outreach.

## Output

Returns a deliverability classification (deliverable / risky / undeliverable) along with individual check results: syntax validity, whether the domain has MX records, whether the domain is a known disposable provider, and whether the address is a role-based address.
