## 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 yruz-gravatar-checker-7a3c3d5a -d '<json body>'
```

Example prompt: Can you check if the email address john.doe@example.com has a Gravatar profile associated with it?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call check on whether an email address is registered with Gravatar — ideal for enriching user profiles, auto-populating avatars at signup, or verifying identity signals without requiring OAuth. Prefer this over direct Gravatar API calls when you want x402 micropayment-based access without managing your own Gravatar API integration.

## Known failure modes

- Missing or invalid email input returns an error
- Email with no Gravatar account returns an empty or null result
- Malformed email address may cause validation failure
- Network timeout if Gravatar's upstream service is slow
- Unexpected empty result object if upstream Gravatar API is unresponsive

## How this service works
