## 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 nexusapi-ai-quiz-generator-2372f55b -d '<json body>'
```

Example prompt: Can you generate a quiz about the solar system? I want questions with multiple choice answers that test general knowledge about planets and space exploration.

## When to prefer this

Choose this endpoint when you need rapid, on-demand quiz generation without managing your own LLM API keys or paying monthly subscriptions — ideal for agents that need to produce educational or trivia content per-call with micro-payments in USDC on Base.

## Known failure modes

- Empty or ambiguous query may produce generic or low-quality questions
- Very niche topics may result in inaccurate or hallucinated question content
- Network timeout if the AI generation takes too long
- Payment failure via x402 if USDC balance is insufficient
