## 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-bing-serp-search-via-x402-16292917 -d '<json body>'
```

Example prompt: Search Bing for 'best open-source LLM frameworks 2024' and give me the top results — titles, URLs, and snippets.

## When to prefer this

Choose this endpoint when you need Bing-specific SERP results (distinct ranking and index from Google) in an agent workflow that already handles x402 micropayments, or when you want pay-per-call pricing with no subscription commitment at $0.01 per search.

## Known failure modes

- Payment failure: x402 micropayment not settled, request blocked with 402 Payment Required
- Invalid query parameters: malformed query object returns upstream error
- Bing API quota exceeded: upstream rate limit or key error returned
- Missing required path or query fields: empty or null query yields no results
- Network timeout: upstream Bing API unresponsive, gateway timeout returned
