## 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 nova-email-validator-e73f6ca2 -d '<json body>'
```

Example prompt: Can you validate the email address 'agent@example.com' and tell me if it's syntactically correct and what domain it belongs to?

## When to prefer this

Use this endpoint when you need lightweight, low-cost ($0.01 USDC) programmatic email syntax validation and normalization in an agent workflow, especially when you want a machine-payable x402-compatible utility without setting up your own validation library or managing dependencies.

## Known failure modes

- Missing or empty email field returns a validation error
- Malformed request body may return a 400 or 422 error
- Payment failure via x402 protocol returns a 402 Payment Required response
- Extremely unusual unicode or internationalized email formats may yield unexpected normalization results

## How this service works

Machine-facing pay-per-call utility services using x402 on Base with USDC.

## Output

Returns a JSON object containing the original email, the extracted domain, the normalized canonical form of the email, and a boolean indicating whether the syntax is valid.
