## 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 quantaflow-google-play-product-serp-api-71cf8b08 -d '<json body>'
```

Example prompt: Search Google Play Store for 'meditation apps' and give me the top results including ratings, developer names, and install counts.

## When to prefer this

Use this endpoint when you need programmatic access to Google Play Store search results or app product pages without managing your own SERP infrastructure, and you are operating in a web3/crypto-native environment where per-call micropayments via x402/USDC are acceptable. Prefer this over manual scraping or expensive subscription SERP APIs for lightweight, on-demand Play Store lookups.

## Known failure modes

- Payment failure — insufficient USDC balance or x402 protocol error results in 402 Payment Required
- Invalid query parameters — malformed path or query object returns an error from the upstream provider
- Upstream SERP provider unavailable — gateway may return 502 or 503
- Rate limiting by underlying provider — may return 429 if upstream quota exceeded
- Empty results — valid query returns no matching apps for the given search term

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream Google Play Store SERP response including app listings, titles, ratings, developer names, install counts, prices, and other product metadata as a passthrough JSON payload from the underlying SERP provider.
