## When to prefer this

Use this endpoint when you need Bing-specific search rankings, want to cross-reference Google results with an alternative ranking signal, or when Google data is insufficient or unavailable. Also useful for SEO research comparing ranking differences between search engines.

## Known failure modes

- Missing required query parameter 'q' returns validation error
- Invalid or empty query string returns no results
- Requesting more than 100 results exceeds the max limit
- Network timeout if Bing is slow to respond
- Rate limiting or payment failure returns 402
