Example prompt: Can you hit that Ratatouille demo hello endpoint and get back the greeting and timestamp it returns?

## When to prefer this

Use this endpoint when you need to test x402 micropayment API connectivity, verify a demo hello-world service is live, or validate that a paid GET request flow works end-to-end. Not suitable for production data retrieval or any real business logic.

## Known failure modes

- Service unavailable if the demo server is down (5xx error)
- Payment failure if insufficient USDC balance for x402 protocol
- Network timeout if the endpoint is unreachable
- Unexpected response format if the demo service changes its output schema

## How this service works

Ratatouille demo hello world: returns a greeting and a timestamp.

## Output

A greeting string (e.g. 'Hello, World!') and a current server timestamp, returned as a JSON object from the demo endpoint.
