DeepSeek has opened the capabilities behind its app as standalone APIs: Search and Fetch, OCR, ASR for speech recognition and TTS for speech synthesis. Tool use is billed on top of tokens, according to DeepSeek's pricing page.

chat-demo client

To demonstrate the APIs, DeepSeek open-sourced chat-demo, a static web client that connects straight from the browser to the API. It supports deep thinking, search, link reading, attachments and voice input. It can also import a user's DeepSeek chat history.

Tool pricing

Per DeepSeek's pricing page:

Tool Price
Search (text or images) $0.75 per 1,000 calls (5 yuan on the China site)
Web fetch $0.75 per 1,000 calls (5 yuan on the China site)
File parsing and OCR $0.225 per 1,000 pages
Text-to-speech $0.45 per 10,000 characters
Speech recognition $0.116 per hour of audio

Both text-to-speech and speech recognition are currently half price. Search and fetch fees apply whether developers call those APIs directly or the model uses them through its tools.

Relationship to earlier release

The release extends the standalone Search and Fetch APIs that DeepSeek opened on October 17, which run on its in-house search engine.

Token prices for deepseek-flash are unchanged: $0.30 per million cache-miss input tokens and $1.20 per million output tokens at peak hours, with off-peak rates at half those levels.

Sources: the official DeepSeek API change log, the official DeepSeek models and pricing page, the official chat-demo repository, and an IT Home report, as summarized by Pandaily.

What this means

Developers can now call search, page fetching, document parsing, OCR and voice as separate services rather than only through the DeepSeek app. The chat-demo repository provides a reference client that uses these features together. Because search and fetch fees apply whether the APIs are called directly or the model invokes them as tools, any application that enables the model's search tools will incur those per-call charges in addition to token costs.
