## 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 fastaf-bing-web-search-api-266b032b
```

Example prompt: Search Bing for 'best electric vehicles 2025' and give me the top 10 results — titles, links, and snippets — targeting the US market with moderate safe search.

## When to prefer this

Choose this endpoint when you specifically need Bing-indexed web results rather than Google results — useful for diversity of sources, Microsoft ecosystem integration, or when Google SERP data is unavailable. Prefer this over sibling endpoints for general web research where you need ranked links with snippets rather than images, shopping results, or AI-generated answers.

## Known failure modes

- Missing required 'query' parameter returns an error
- Invalid or unsupported market code (mkt) may return no results or an error
- Payment not received or insufficient USDC balance causes 402 rejection
- Overly broad queries may return low-relevance results
- Rate limiting if too many requests are made in short succession
- Empty results if query terms have no matching Bing index entries
