## How to call it through Zero

```sh
zero fetch --capability agentdiet-email-verification-6a210b85
```

Example prompt: Can you verify whether john.doe@acme.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 a lightweight, pay-per-call email verification check without a subscription, particularly in agent workflows that need real-time validation at the point of data entry or lead enrichment. Best suited for single-address lookups via a micropayment model using x402/USDC, rather than bulk batch verification services.

## Known failure modes

- Invalid or malformed email address input returns an error status
- Unresolvable domain results in domain-not-found or DNS failure signal
- Catch-all mail servers may return inconclusive deliverability results
- Rate limiting or payment failure (HTTP 402) if USDC payment is not attached
- Temporary SMTP timeouts may yield uncertain results for some providers

## 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), deliverability assessment, and metadata about the email address including whether the mailbox exists, domain is valid, and any risk signals. The response mirrors the hub's standard envelope with a data payload and status field.
