## 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 agentsvc-io-email-validator-31f8a970 -d '<json body>'
```

Example prompt: Can you check whether 'john.doe@acme-corp.com' is a real, deliverable email — tell me if the format is valid, the domain has MX records, and whether it's a disposable or role address?

## When to prefer this

Choose this endpoint when you need lightweight, per-call email validation without setting up an account or API key, and want to pay only $0.002 USDC per check via x402 on Base. It is ideal for agents that need to validate individual emails on-demand — e.g. at signup, before outreach, or during list hygiene — and need both syntax and deliverability signals including MX records and disposable-address detection.

## Known failure modes

- Invalid or malformed email format provided — API may return format_valid: false or an error
- Domain does not exist or has no MX records — is_valid will be false with domain_has_mx: false
- Network timeout when performing MX lookup for obscure domains
- Empty or missing email field in request body — likely returns a validation error
