## 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-serp-search-de8a47e4 -d '<json body>'
```

Example prompt: Search Google Play Store for 'meditation apps' and show me the top results including app names, ratings, and developer info.

## When to prefer this

Use this endpoint when you need to programmatically search Google Play Store results and are comfortable with x402 micropayment-based access at $0.01 USDC per call. Prefer this over manual scraping when you need a pay-as-you-go model with no monthly subscription, especially in Web3-native or agent-driven workflows where USDC micropayments are natural.

## Known failure modes

- Payment failure or insufficient USDC balance causing 402 response
- Invalid or malformed query parameters causing upstream error
- Google Play rate limiting or blocking resulting in empty or error response
- Malformed path causing routing error to wrong upstream endpoint
- Upstream SERP service unavailability returning 5xx error

## How this service works

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

## Output

The upstream Google Play SERP response is passed through directly after successful x402 micropayment, typically containing a list of app listings with titles, ratings, developer names, descriptions, and other metadata from the search results page.
