This guide walks through registration, activation and calling steps.
Use Cases
For developers and operators who need a traceable, real-time, multilingual search capability for content sites, AI applications or automated workflows. DeepSeek Search is an AI-native general-purpose search engine; both the web app and the API are powered by the same in-house engine, which DeepSeek says handles hundreds of millions of search requests per day.
