DeepSeek API

Integrate language models, tool calls and structured outputs into an application through an API.

DeepSeek API is a model interface for developers. Its documentation covers compatible request formats, streaming, tool calls and pricing. It suits developers with an existing app who want to compare model services. This entry describes the API product; conditions for a general chat service are not API allowances.

Main features

• Conversation and streaming APIs
• Structured output and tool calling
• Developer documentation and model pricing

Who it is for and what to check

• App developers
• AI integration teams
• You must manage API keys, errors and usage limits.
• Pricing differs by model, input, output and caching.

API charges depend on the model and token usage; these are not the chat product's prices.
