## 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 minerva-email-validation-572bae17 -d '<json body>'
```

Example prompt: Can you check whether these email addresses actually exist: john.doe@example.com, jane.smith@acme.org, and test@fakebusiness.net? I want to know which ones are real before I send outreach.

## When to prefer this

Use this endpoint when you need to verify whether specific email addresses actually exist before sending communications, enriching a CRM, or cleaning a contact list. Prefer this over general enrichment endpoints when the primary goal is deliverability or existence checking rather than profile data. Supports up to 2000 emails per call, making it suitable for batch list cleaning workflows.

## Known failure modes

- Empty or missing records array returns a validation error
- Submitting more than 2000 emails in a single request exceeds the batch limit
- Malformed email strings may return is_match: false rather than an error
- Temporary provider outage may result in failed or incomplete results
- Unknown or newly created email addresses may return null for email_last_seen and email_validation_status

## How this service works

Pay-per-request access to FullEnrich, CompanyEnrich, LeadMagic, Clado, Exa, Firecrawl, Google Maps, Serper, and Whitepages APIs. No auth, no subscriptions.

## Output

Returns an array of results for each submitted email address, each containing: the email address, a boolean is_match indicating whether the address is valid/exists, an optional email_validation_status string, and an optional email_last_seen timestamp. Also includes a request ID and completion timestamp.
