## 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-google-shopping-product-price-history-a38fb275
```

Example prompt: Can you pull up the price history for the Sony WH-1000XM5 headphones on Google Shopping so I can see how the price has changed over the past few months?

## When to prefer this

Choose this endpoint when you need historical price trend data specifically from Google Shopping for consumer electronics, appliances, or other retail goods. Ideal for price-drop detection, deal verification, purchase timing optimization, or building price-aware shopping agents. Prefer this over generic web scraping when you need structured, time-series price data without managing your own scraping infrastructure, and when per-call x402 micropayment pricing (no subscription) is preferable.

## Known failure modes

- Product not found on Google Shopping returns empty or null price history
- Invalid or malformed product identifier/URL returns an error
- Product with insufficient price history returns limited data points
- Payment failure via x402 protocol prevents endpoint access
- Rate limiting or Google-side blocking may return incomplete data
- Newly listed products may have no historical data available
