## 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 gravatar-check-895fa46b
```

Example prompt: Can you check if the email john.doe@example.com has a public Gravatar avatar and profile, and give me the avatar and profile URLs if it does?

## When to prefer this

Prefer this endpoint when you need to check for a Gravatar avatar using an email address while preserving privacy (only the SHA-256 hash is transmitted to Gravatar, not the raw email). Ideal for contact enrichment workflows, CRM tools, or user profile displays where you want a real avatar without storing or exposing PII. Use this over direct Gravatar API calls when you want a simple, pay-per-use HTTP check without managing hashing logic yourself.

## Known failure modes

- Email has no associated Gravatar account — returns a not-found or empty result
- Invalid or malformed email address provided — may return an error or hash mismatch
- Gravatar service is unreachable — upstream timeout or connectivity error
- Rate limiting or payment failure — HTTP 402 or 429 response if credits are exhausted

## How this service works

Gravatar check: whether an email address has a public Gravatar avatar and profile (via the SHA-256 hash, no data sent to third parties beyond the hash), with the avatar and profile URLs. Enrich contacts with a real avatar. $0.01 per address.

## Output

Returns whether the given email address has a public Gravatar avatar and profile, along with the avatar image URL and the Gravatar profile URL if they exist. The lookup is performed via the SHA-256 hash of the email address, so the raw email is never sent to Gravatar's servers.
