## 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 agentdiet-email-verification-5d100be7
```

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

Use this endpoint when you need fast, affordable email verification ($0.005 USDC per call) for B2B lead enrichment or pre-send validation workflows. Prefer this over general OSINT tools when the primary goal is confirming email deliverability specifically, especially in agent pipelines that already use x402/Base USDC micropayments.

## Known failure modes

- Invalid or malformed email address format returns an error status
- Non-existent domain results in failed verification
- Catch-all mail server configurations may return inconclusive results
- Rate limiting if too many requests are made in quick succession
- Payment failure via x402/USDC prevents the call from completing
