## 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-562013c6
```

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

## When to prefer this

Choose this endpoint when you need lightweight, per-address email verification at $0.005 USDC per call via x402 micropayment, especially in agent pipelines that require B2A-native payment flows. Ideal for validating individual email addresses during lead enrichment, sign-up screening, or CRM hygiene tasks where cost-per-call matters and you want agent-ready distilled JSON output rather than a heavy verification platform subscription.

## Known failure modes

- Invalid or malformed email format returns an error status
- Catch-all mail servers may report inconclusive deliverability
- Temporary DNS or SMTP lookup failures may yield uncertain results
- Disposable email detection may lag newly created throwaway domains
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not fulfilled

## 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

Returns a JSON object with verification status ('ok'), and data containing the email's validity, deliverability, whether the domain accepts mail, whether the mailbox exists, and any risk signals such as disposable or role-based addresses. Includes token-efficiency metadata (distilled_tokens, compression_ratio_pct) reflecting the distilled response format.
