## 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 apexapi-ai-quiz-generator-1362c3f4 -d '<json body>'
```

Example prompt: Can you generate a quiz about the history of the Roman Empire? Give me a set of questions I can use to test someone's knowledge on the topic.

## When to prefer this

Use this endpoint when you need AI-generated quiz or trivia questions on a specific topic and want a pay-per-call model with no API key setup. Prefer over alternatives when working in a crypto-native, USDC-on-Base payment context.
