## 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 openweb-ninja-walmart-product-reviews-api-0f53c11b
```

Example prompt: Can you pull the latest customer reviews for the Walmart product with ID 123456789 — I want to see what shoppers are saying, including star ratings and review text?

## When to prefer this

Choose this endpoint when you need real-time Walmart product review data without managing API keys or subscriptions — ideal for agents that need on-demand, pay-per-call access to Walmart customer sentiment. Prefer over manual scraping or subscription-based APIs when request volume is low or unpredictable and cost-per-call pricing ($0.003 USDC) is preferable to monthly fees.

## Known failure modes

- Invalid or non-existent Walmart product ID returns empty results or error
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Walmart rate limiting or anti-scraping measures may cause intermittent failures
- Product with no reviews returns an empty reviews array
- Network timeout if Walmart's site is slow to respond
