zero fetch --capability omniapi-ai-quiz-generator-0f0c9a0a -d '<json body>'

## When to prefer this

Choose this endpoint when you need programmatically generated quiz or trivia questions on a specific topic and want to pay only per call via USDC micropayment. Best suited for agents automating educational content creation, training material generation, or trivia assembly without a subscription model.

## Known failure modes

- Missing required 'query' field returns validation error
- Insufficient USDC balance or x402 payment failure blocks the call
- Overly vague query may produce generic or low-quality questions
- Network timeout on Vercel serverless cold start
- Rate limiting if too many sequential calls are made
