## 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 yu-gi-oh-set-card-lookup-4958fd95 -d '<json body>'
```

Example prompt: What Yu-Gi-Oh! card is SDY-001, and what rarity and market price does it have?

## When to prefer this

Use this endpoint when you need to identify a specific Yu-Gi-Oh! card by its set code (e.g. SDY-001) and need rarity and market pricing data alongside it. Prefer this over general card search endpoints when you already have the set code and need precise lookup.

## Known failure modes

- Invalid or malformed set code returns an error or empty result
- Unknown set code not found in database returns null or 404
- Missing query parameter q returns a bad request error
