## How to call it through Zero

```sh
zero fetch --capability agentdiet-email-verification-7b8c598d
```

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 fast, pay-per-use email verification check integrated into an agent workflow with crypto micropayment (x402 Base USDC) support, particularly when enriching B2B leads or cleaning contact lists without committing to a bulk subscription service.

## Known failure modes

- Invalid or missing email parameter returns an error response
- Temporary DNS lookup failures may produce inconclusive results
- Disposable or catch-all domains may return ambiguous deliverability signals
- Payment failure via x402/USDC results in HTTP 402 and no verification result
- Malformed email addresses return syntax error before any DNS check

## 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 (valid/invalid/risky), deliverability assessment, and metadata about the email address such as whether it is disposable, role-based, or syntactically malformed.
