## 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-search-9383b794 -d '<json body>'
```

Example prompt: Search Google News for the latest articles about Ethereum ETF approval and return the top headlines and publication sources.

## When to prefer this

Choose this endpoint when you need programmatic access to Google News search results on a pay-per-use basis without a monthly subscription, especially in web3/DeFi agent workflows where micropayments via x402 protocol are already integrated. It is ideal for lightweight, infrequent news lookups where per-call $0.01 USDC pricing is more cost-effective than committing to a recurring SERP API plan.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402 Payment Required
- Invalid or missing query parameters return 400 Bad Request
- Upstream SERP API rate limit or unavailability returns 502 or 503
- Malformed JSON body results in request forwarding failure
- Empty or overly broad query may return low-relevance results

## How this service works

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

## Output

Returns the upstream Google News SERP response body passed through after successful x402 micropayment, typically including news article titles, URLs, snippets, publication dates, and source names as structured search results.
