## 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 zeroclick-x402-service-registry-product-search-97f619de -d '<json body>'
```

Example prompt: Search for new wireless gaming mice between $20 and $80 across major retailers and show me the top 10 results with prices, ratings, and where to buy them.

## When to prefer this

Use this endpoint when you need real-time product prices and availability across multiple major retailers in a single call, especially for price comparison, shopping research, or product discovery. Prefer this over scraping individual retailer sites or using general web search when structured product data (price, rating, delivery) is required. The Google Shopping backend ensures broad retailer coverage including Amazon, Walmart, Best Buy, Target, and eBay.

## Known failure modes

- No results found for very niche or misspelled queries — returns empty results array
- Invalid price range (minPrice > maxPrice) may return unexpected results or an error
- Query string too long (over 200 characters) will be rejected
- Retailer links may occasionally be empty strings in the response
- Prices may be null for some products if not available from the source
