## 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-bing-news-search-546a16c5 -d '<json body>'
```

Example prompt: Search Bing news for the latest articles about the Federal Reserve interest rate decision and return the top headlines and links.

## When to prefer this

Choose this endpoint when you need programmatic access to Bing News SERP results and want to pay via USDC micropayments using the x402 protocol rather than managing a traditional Bing Search API subscription key. Ideal for AI agents operating in web3/DeFi environments that natively support x402 payment flows.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted, returning 402 Payment Required
- Invalid query parameters: malformed path or query object causing upstream errors
- Upstream Bing API rate limit or outage causing 502/503 passthrough
- Empty results: query returns no matching news articles
- Network timeout from Vercel gateway to upstream Bing service

## How this service works

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

## Output

The passthrough upstream response from the Bing News SERP API, typically including a list of news articles with titles, URLs, descriptions, publication timestamps, and source names, as returned by the underlying Bing News Search service.
