## When to prefer this

Choose this endpoint when you need keyword extraction specifically backed by Baidu's NLP models, which are well-optimized for Chinese-language text. It is ideal for agents processing Chinese content pipelines, SEO workflows, content tagging systems, or market research on Chinese-language data. At $0.001 per call with 50 free daily calls, it is cost-effective for high-frequency extraction tasks. Prefer this over generic NLP APIs when Chinese language fidelity and Baidu's proprietary language model quality are important.

## Known failure modes
