## 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 omniapi-ai-flashcard-generator-18602d76 -d '<json body>'

## When to prefer this

Choose this endpoint when you need on-demand AI-generated flashcards for any topic without building your own generation pipeline, and you're operating in a pay-per-call x402 environment. It is particularly useful for agents building lightweight educational tools, study assistants, or content summarizers where USDC micro-payment billing is already integrated.

## Known failure modes

- Missing required 'query' field returns a validation error
- Vague or very short queries may produce low-quality or irrelevant flashcards
- Payment failure via x402 returns HTTP 402 and no content is delivered
- Overly broad topics may yield generic cards with low educational value
- Rate limits or server-side errors may return 500 responses
