## 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 agentrxi-email-verification-05989a76
```

Example prompt: Before I add this lead to my CRM, can you check whether john.doe@tempmail.com is a real deliverable address or a disposable/role account?

## When to prefer this

Use this endpoint when you need a lightweight, fast, multi-signal email check — syntax, MX, disposable, and role-account — in a single pay-per-call API with no subscription. Ideal for agents that encounter user-submitted emails at runtime (signups, CRM entry, campaign lists) and need a quick go/no-go signal without setting up a dedicated email validation service.

## Known failure modes

- Missing or malformed email parameter returns a 400-style error
- Domain has no MX records — deliverability check fails but syntax may still pass
- Disposable domain list may not include every new throwaway provider
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Legitimate domains occasionally misidentified as disposable due to shared infrastructure

## How this service works

Verify an email address: syntax check, domain MX lookup, disposable-domain and role-account flags. Use before sending or storing an address.

## Output

Returns structured flags for the queried email address: whether the syntax is valid, whether the domain has valid MX records (indicating deliverability), whether the domain is a known disposable/temporary email provider, and whether the address is a role account (e.g. info@, support@, noreply@).
