## 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-serp-apple-reviews-gateway-d4bff555 -d '<json body>'
```

Example prompt: Can you pull the latest Apple App Store reviews for the Spotify app so I can see what users are saying about recent updates?

## When to prefer this

Choose this endpoint when you need Apple App Store review data on a pay-per-call basis without a subscription, especially when integrating into a web3/DeFi-native agent workflow that supports x402 micropayments. Ideal for infrequent or on-demand App Store review lookups where a recurring SaaS subscription is not cost-effective.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 protocol error returns payment-required error
- Invalid app identifier or path returns empty results or upstream 404
- Upstream SERP provider unavailable returns gateway error
- Malformed query parameters result in no reviews returned
- Rate limiting from upstream Apple review data source

## 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 review data including review text, star ratings, reviewer metadata, and related SERP-scraped review fields, passed through directly from the upstream SERP provider after successful x402 micropayment processing.
