Example prompt: Can you pull up the list of Amazon product categories available on the US Amazon marketplace so I can pick the right category ID before searching for products?

## When to prefer this

Use this endpoint when you need valid category_id values to pass into an Amazon Product Search query. It is the authoritative source of browsable Amazon category IDs per marketplace and should always be called before filtering Product Search by category to avoid using invalid or stale category identifiers.

## Known failure modes

- Invalid or unsupported country code returns an error or empty data array
- Network timeout from upstream Amazon data provider
- Upstream Amazon marketplace temporarily unavailable causing failed request
- Missing country parameter defaults to US but may not match intended marketplace
