## 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-566d5195
```

Example prompt: Can you verify whether john.doe@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 a lightweight, pay-per-call email verification integrated with x402/Base USDC micropayments, especially within an agent workflow that already uses the AgentDiet B2A suite for lead enrichment or domain OSINT. Prefer this over bulk verification services when validating individual emails in real time during outreach preparation or user onboarding.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Unresolvable or disposable email domains may return inconclusive results
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Temporary DNS lookup failures may cause intermittent validation errors

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output
