## 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-amazon-product-serp-search-a7a3b589 -d '<json body>'
```

Example prompt: Search Amazon for 'wireless noise-cancelling headphones under $100' and give me the top product listings with their titles, prices, and ratings.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-use access to Amazon product search results without a subscription commitment, particularly in Web3/DeFi agent workflows where x402 micropayments are already supported. At $0.01 USDC per call it is cost-effective for occasional lookups. Prefer alternatives (dedicated SERP API subscriptions) for high-volume batch searches where per-call pricing becomes expensive.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 protocol handshake failure returns 402 Payment Required
- Invalid query: malformed path or query parameters return upstream error
- Rate limiting: upstream Amazon SERP provider throttles repeated identical queries
- No results: rare but possible for very niche or misspelled queries
- Upstream unavailability: QuantaFlow gateway or underlying SERP provider is down, returning 502/503

## How this service works

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

## Output

Returns Amazon SERP data including product listings with titles, prices, ratings, review counts, ASINs, image URLs, and product page links for the queried search term, passed through from the upstream SERP provider after successful $0.01 USDC x402 payment.
