DeepSeek releases comprehensive API suite, enabling full replication of DeepSeek app functionality

DeepSeek announced the official release of its full suite of application APIs on November 13, 2026. This update integrates various interactive features of the DeepSeek App directly into the existing API structure by enabling specific parameters. Developers can now achieve complex conversational capabilities, allowing for a near one-to-one replication of the complete DeepSeek App within their own applications. The V4.1-Flash model (deepseek-flash) supports several advanced functionalities via the Messages, Responses, and Chat Completions interfaces. These include web search capabilities—both standard and multi-step deep thinking search—as well as file input for parsing documents like PDFs and Office files. The API also supports reading content from provided URLs using the deepseek_read_url tool. Furthermore, the platform offers independent interfaces for underlying capabilities such as Search, Fetch, OCR, ASR, and TTS, providing flexible integration options. A safety parameter is available to enable basic risk control and content moderation for external service providers. DeepSeek has also provided a lightweight frontend demo and example code for developers to test these new features. Usage of these extended capabilities incurs charges beyond standard Token fees.
