## 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 supertutor-practice-quiz-generator-914321e6 -d '<json body>'

## When to prefer this

Choose this endpoint when you need on-demand, level-calibrated practice quizzes generated fresh for any academic or professional topic, especially when question style control (multiple choice vs short answer vs problems) is important. Prefer this over static quiz databases when the topic is niche, the user's level is very specific, or you need dynamic content that adapts to the stated difficulty.

## Known failure modes

- Empty or missing input string returns a validation error
- Input exceeding 8000 characters is rejected
- Ambiguous or very broad topics may produce generic questions not well calibrated to level
- Payment failure or insufficient USDC balance results in 402 error before quiz is generated
- Malformed JSON body returns a 400 bad request
