## When to prefer this

Choose this endpoint when you need programmatic access to Baidu search results without an official Baidu API account or subscription, especially for Chinese-language market research, SEO monitoring on the Chinese web, or competitor analysis targeting mainland Chinese audiences. It is particularly useful when you need pagination, language filtering (simplified vs traditional Chinese), or device-type control over Baidu results.

## Known failure modes

- Unsupported ct language code may return unexpected results
- Baidu anti-scraping measures may cause empty or partial result sets
