## 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-lead-email-verify-5b87b19b -d '<json body>'
```

Example prompt: Can you verify whether john.smith@acmecorp.com is a real, deliverable email address before I add it to my outreach list?

## When to prefer this

Choose this endpoint when you need verified, auditable email validation with a cryptographic audit trail — particularly useful in regulated industries or compliance-sensitive workflows. Prefer it over generic email syntax checkers when you need real deliverability confirmation (SMTP-level checks), not just format validation. The $0.216 price point reflects deeper verification than basic regex or DNS-only checks.

## Known failure modes

- Invalid email format returns a format error before network checks
- Unresolvable domain (DNS failure) results in undeliverable status
- Catch-all mail server configurations may yield indeterminate results
- Temporary SMTP errors may cause inconclusive responses
- Malformed input (missing @ symbol, null value) returns a 400-level error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a validation result indicating whether the email address is valid, deliverable, and safe to use, along with an audit record containing a cryptographic chain hash for traceability and compliance.
