## 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 datanexusai-hearthstone-cards-by-class-12659825
```

Example prompt: Pull all collectible Mage cards from the Hearthstone database and limit the results to 50.

## When to prefer this

Use this endpoint when you need structured Hearthstone card data scoped to a single class, especially for deck-building tools, game wikis, or card comparison applications. Prefer over a general card search endpoint when class is the primary filter dimension.

## Known failure modes

- Invalid card_class value returns empty results or 404
- Missing card_class path parameter causes a 400 or routing error
- Payment failure (x402) if USDC micropayment is not completed or insufficient funds
- limit parameter out of range may return an error or be silently capped
- Non-existent class name returns empty array
