## 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-product-search-api-x402-openwebninja-com-8aaf9a3d
```

Example prompt: Search Walmart for 'wireless earbuds' under $50, sorted by top rated, in the US — give me the first page of results including prices, ratings, and whether they're in stock.

## When to prefer this

Use this endpoint when you need real-time Walmart product search results with rich metadata including pricing, availability, ratings, and seller info. Prefer over static datasets when current inventory and pricing accuracy matter. Choose this over general web search when you need structured, machine-readable product data specifically from Walmart rather than aggregated shopping results.

## Known failure modes

- Missing required 'query' parameter returns a validation error
- Invalid domain enum value (not 'us' or 'ca') returns a schema error
- Invalid sort_by value returns a schema error
- Page number below 1 returns a validation error
- Query returns zero results when no products match filters
- Payment failure or insufficient USDC balance returns a 402 error
- Walmart site unavailability may cause upstream timeout or empty response
