## 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-product-search-api-b2d678e3
```

Example prompt: Search Walmart for 'wireless noise-cancelling headphones' in the US, sorted by top rated, with a max price of $150 — show me the first page of results.

## When to prefer this

Use this endpoint when you need real-time Walmart product search results including live pricing, availability, and seller data. Prefer this over static datasets when freshness matters — e.g. price comparison, stock checking, or shopping automation. Best suited for US and Canadian Walmart markets. Supports filtering by price range, ZIP code, store, and sort order for targeted shopping queries.

## Known failure modes

- Missing required 'query' parameter returns a validation error
- Invalid domain value (not 'us' or 'ca') causes a schema error
- Invalid sort_by enum value causes a schema error
- No results found for niche or misspelled query returns empty products array
- Walmart rate-limiting or anti-bot detection may cause upstream failures
- Payment failure or insufficient USDC balance results in 402 error
