3. Parameters

3.1 Header Parameters

Parameter	Type	Required	Description	Example
Content-Type	string	Yes	Sets the request content type. It must be application/json	application/json
Accept	string	Yes	Sets the response content type. The recommended value is application/json	application/json
Authorization	string	Yes	API key required for authentication, in the format Bearer $YOUR_API_KEY.	Bearer $YOUR_API_KEY

3.2 Body Parameters (application/json)

Parameter	Type	Required	Description	Example
model	string	Yes	The model ID to use. See Model List for available versions, such as deepseek-v3.	deepseek-v3
messages	array	Yes	A chat message list in an OpenAI-compatible format. Each object contains role and content.	[{"role": "user","content": "Hello"}]
role	string	No	Message role. Supported values: system, user, and assistant.	user
content	string	No	The message content.	Hello, tell me a joke.
temperature	number	No	Sampling temperature in the range 0-2. Higher values make the output more random, while lower values make it more focused and deterministic.	0.7
top_p	number	No	Another way to control the sampling distribution, in the range 0-1. It is usually used instead of temperature.	0.9
n	number	No	How many completions to generate for each input message.	1
stream	boolean	No	Whether to enable streaming output. When set to true, the API returns ChatGPT-style streamed data.	false
stop	string	No	You can specify up to 4 stop strings. Generation stops when one of them appears in the output.	"\n"
max_tokens	number	No	The maximum number of tokens that can be generated in a single reply, subject to the model context window.	1024
presence_penalty	number	No	-2.0 to 2.0. Positive values encourage the model to introduce new topics, while negative values reduce that tendency.	0
frequency_penalty	number	No	-2.0 to 2.0. Positive values reduce repetition, while negative values increase it.	0
