## 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-google-news-light-19f484b2 -d '<json body>'
```

Example prompt: Search Google News for the latest articles about 'Federal Reserve interest rate decision' and give me the top headlines and sources.

## When to prefer this

Choose this endpoint when you need programmatic access to Google News SERP results on a lightweight pay-per-call basis without managing a subscription or API key. It is ideal for agents that need fresh news headlines on demand, for one-off or low-volume queries, or when operating in a web3/crypto-native payment context where USDC micropayments via x402 are already supported. Prefer this over full SERP suites when you only need news (not web, images, or shopping results) and want minimal cost per call.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance returns a 402 error
- Invalid query: missing or malformed query parameters may return an empty result set or upstream error
- Rate limiting: upstream Google News SERP proxy may throttle high-frequency requests
- Upstream unavailability: the proxied news SERP service may be temporarily down, returning a 502 or 503
- Stale results: news results reflect the moment of request and may lag breaking events by minutes

## How this service works

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

## Output

Returns the upstream SERP response from a Google News search, typically including article titles, source names, publication timestamps, snippet text, and URLs for the top news results matching the query, passed through as-is from the proxied upstream service.
