## 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-realtime-shopping-search-serp-api-3120ba2c
```

Example prompt: Search Google Shopping right now for 'Sony WH-1000XM5 headphones' and give me the top product listings with prices and merchant names.

## When to prefer this

Choose this endpoint when you need live, real-time shopping search results (prices, merchants, product listings) without maintaining an API key or subscription. Ideal for agents that need pay-per-call pricing ($0.003 USDC) and on-demand access to shopping SERP data across multiple supported blockchains (Base, Polygon, Arbitrum). Prefer this over scraping or browser automation when structured JSON output and low per-call cost matter.

## Known failure modes

- Missing or invalid query parameter returns an error response
- Payment failure via x402 (insufficient USDC balance) results in 402 Payment Required
- Rate limits or upstream SERP provider outages may cause transient failures
- Query returning no results yields an empty results array
- Malformed request schema returns a 400 Bad Request
