## 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-via-x402-broker-f5436a73
```

Example prompt: Can you verify whether john.smith@acmecorp.com is a real, deliverable email address using the AgentDiet hub — pay the micro-fee automatically and tell me if it's valid?

## When to prefer this

Choose this endpoint when you need email verification with automatic per-call micropayment billing via x402 Base USDC, especially within an agentic workflow that already uses the AgentDiet B2A hub for other intelligence tasks like lead enrichment or domain OSINT. Prefer it over free validators when you need reliable, paid-tier verification with ROI/compression metrics included in the response.

## Known failure modes

- Invalid or malformed email input returns error status
- Missing required 'input' or 'method' fields causes schema validation failure
- Payment failure via x402 results in HTTP 402 response blocking the call
- Query param 'query' missing may return empty or default data object
- Service unavailability returns non-200 status with no data

## Output
