## 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-b9769e6a
```

Example prompt: Can you verify whether john.smith@acmecorp.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 a quick, pay-per-use email validation check via a crypto-native x402 micropayment flow (Base USDC). It is well-suited for AI agents that need to validate individual email addresses on demand without a traditional API subscription, particularly in B2A or agentic pipeline contexts where autonomous payments are supported.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Invalid email format may return validation failure rather than deliverability result
- Temporary DNS or SMTP lookup failures may cause intermittent errors
- Payment failure via x402/HTTP 402 will block the request if USDC balance is insufficient
- Rate limiting may apply if too many requests are sent in quick succession

## 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 a status field ('ok') and a data object containing verification details about the email address, such as whether it is valid and deliverable. Also includes an roi_proof object with a compression_ratio_pct indicating the efficiency of the distillation.
