## 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 strale-contact-verify-11b250b5 -d '<json body>'
```

Example prompt: Can you verify whether jane.doe@acmecorp.com is a real, deliverable email address — and also check that the postal address 123 Main St, Austin TX 78701 and phone +15125550199 are valid? I need a full audit trail for compliance.

## When to prefer this

Use this endpoint when you need multi-field contact verification (email plus optional address and phone) with structured JSON output and audit trails, particularly for compliance, KYC, or trust-and-safety workflows. Prefer it over single-purpose email validators when you need all three contact signals validated together with a documented audit record.

## Known failure modes

- Invalid or malformed email format returns a validation error
- Unresolvable domain for email results in a failed deliverability check
- Postal address not found in reference data returns unverified status
- Phone number in unsupported format or region returns an error
- Missing required email field returns a 400-level error
- Network timeout or upstream data provider outage returns a 5xx error

## How this service works

Verify a contact's email, phone number, and address in parallel. Returns validation status for each channel. Essential for CRM hygiene and lead qualification.

## Output

A structured JSON object indicating whether each provided contact field (email, address, phone number) is valid, along with verification details and an audit trail for compliance purposes.
