Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

## When to prefer this

Use this endpoint when you want to retrieve a simple 'Good Night' greeting message programmatically without an API key, paying only $0.001 USDC per call via the x402 micropayment protocol on Base. Ideal for novelty, testing x402 pay-per-call flows, or embedding GN greetings in automated workflows.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or missing x402 payment header — request rejected
