## 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-apple-app-store-serp-search-c8ee63c2 -d '<json body>'
```

Example prompt: Search the Apple App Store for meditation apps and show me the top results including their names, ratings, and descriptions.

## When to prefer this

Use this endpoint when you need programmatic access to Apple App Store search results via a pay-per-use model without requiring a long-term API subscription. Ideal for AI agents performing one-off or infrequent App Store searches, market research tasks, or competitive intelligence gathering on iOS apps, especially in web3/crypto-native environments where USDC micropayments via x402 are preferred over traditional API key billing.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance, resulting in a 402 response
- Invalid query parameters: malformed path or query object returns an error from upstream
- No results found: search term returns an empty result set from the App Store
- Rate limiting: upstream Apple API throttles the request, returning a rate limit error
- Gateway timeout: upstream App Store search takes too long and the gateway times out
- Invalid JSON body: malformed body string causes a parse error

## How this service works

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

## Output

Returns the upstream Apple App Store SERP response, typically including a list of app listings with metadata such as app names, icons, ratings, developer names, pricing, descriptions, and App Store URLs for apps matching the search query.
