## 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 walmart-real-time-products-by-category-7036ab89
```

Example prompt: Show me the top-rated electronics on Walmart.com — category ID 3944, sorted by top_rated, priced between $50 and $300, near zip code 90210, first page of results.

## When to prefer this

Use this endpoint when you need real-time Walmart product data by category — especially when you need live pricing, availability, ratings, and seller details. Prefer this over static datasets when freshness matters or when filtering by store, zip code, or price range is required. Best for shopping assistants, price comparison tools, or retail analytics workflows targeting Walmart specifically.

## Known failure modes

- Missing required category_id parameter returns a 400 validation error
- Invalid category_id that doesn't exist on Walmart returns an empty products array
- Invalid sort_by value returns a 400 schema validation error
- Payment not provided or insufficient USDC balance returns a 402 Payment Required
- Walmart rate limiting or downtime causes 503 or timeout errors
- Combining min_price and max_price where min > max may return empty results
- Invalid domain enum value (not 'us' or 'ca') returns a validation error
