DeepSeek launches full suite of application APIs for search, file handling and speech

DeepSeek announced a “full suite” of application APIs on November 13, enabling developers to rebuild the core functions of the DeepSeek App inside their own services Pandaily. The deepseek-flash model, which powers DeepSeek-V4.1-Flash-1017, now supports web search, deep-thinking search, file input (PDF, Office, images), URL reading and a safety-check parameter through the Messages, Responses and Chat Completions APIs.

In addition to tool-enabled calls, DeepSeek provides standalone endpoints for Search, Fetch, OCR, automatic speech recognition (ASR) and text-to-speech (TTS). A public chat-demo client demonstrates these capabilities, allowing link reading, attachments and voice input while importing a user’s DeepSeek chat history.

Tool usage is billed on top of token costs. The pricing page lists search and fetch at $0.75 per 1,000 calls (5 yuan on the China site), file parsing and OCR at $0.225 per 1,000 pages, TTS at $0.45 per 10,000 characters and ASR at $0.116 per hour of audio, both currently at half price. Token rates for deepseek-flash remain $0.30 per million input tokens and $1.20 per million output tokens during peak hours.
