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

Choose this endpoint when you need AI-generated study flashcards on demand without managing API keys — ideal for educational agents, tutoring apps, or study assistants that require pay-per-use access with USDC on Base. Prefer this over self-hosted solutions when rapid flashcard generation with no infrastructure overhead is the priority.

## Known failure modes

- Empty or vague query may produce low-quality or irrelevant flashcards
- Very broad topics may result in generic or shallow cards
- Payment failure (HTTP 402) if USDC balance on Base is insufficient
- Rate limiting or server errors if the NexusAPI platform is under load
- Malformed request body returns a 400 error
