## 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 amazon-product-category-list-api-0de6ff79
```

Example prompt: Can you fetch me the full list of Amazon product categories available on the US marketplace so I can see all the department IDs and names?

## When to prefer this

Use this endpoint when you need a structured, programmatic list of Amazon product category IDs and names for a specific country marketplace — particularly useful for building category selectors, seeding product searches, or mapping Amazon taxonomy across supported international storefronts. Prefer this over scraping Amazon directly or using search-based category discovery.

## Known failure modes

- Invalid or unsupported country code returns an error
- Missing required query parameters may return a validation error
- Rate limiting or payment failure returns 402 Payment Required
- Upstream Amazon data unavailability may return empty or partial results
