## 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-check-87464bc9
```

Example prompt: Can you check whether the email address john.doe@example.com is valid using AgentDiet's email check?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation that settles via x402/USDC on Base — ideal for AI agents operating in autonomous B2A or A2A payment contexts where traditional API key management is undesirable. Prefer this over bulk email list validators when validating individual addresses programmatically in agent workflows.

## Known failure modes

- Missing or malformed email query parameter returns an error or empty data object
- Invalid email format may return a non-ok status
- Payment not settled in USDC on Base causes 402 Payment Required response
- Network or node unavailability returns service error
- Disposable or non-existent domains may return negative validation result

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

A JSON object with a 'status' field (e.g. 'ok'), a 'data' object containing email check details, and a 'roi_proof' object showing a compression_ratio_pct value indicating processing efficiency
