代码示例
import os
from openai import OpenAI

client = OpenAI(
    api_key=os.getenv("ATLASCLOUD_API_KEY"),
    base_url="https://api.atlascloud.ai/v1"
)

response = client.chat.completions.create(
    model="deepseek-ai/deepseek-v4-flash-0731",
    messages=[
    {
        "role": "user",

print(response.choices[0].message.content)

安装

安装所需的依赖包。

pip install requests

认证

所有 API 请求需要通过 API Key 进行认证。您可以在 Atlas Cloud 控制台获取 API Key。

export ATLASCLOUD_API_KEY="your-api-key-here"

HTTP 请求头

import os

API_KEY = os.environ.get("ATLASCLOUD_API_KEY")
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}

保护好您的 API Key

切勿在客户端代码或公开仓库中暴露您的 API Key。请使用环境变量或后端代理。

提交请求

import requests

url = "https://api.atlascloud.ai/v1/chat/completions"
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer $ATLASCLOUD_API_KEY"
}
data = {
    "model": "your-model",
    "messages": [{"role": "user", "content": "Hello"}],
    "max_tokens": 1024
}

response = requests.post(url, headers=headers, json=data)
print(response.json())

Input Schema

以下参数在请求体中被接受。

总计: 14必填: 2可选: 12

modelstringrequired

The model ID to use for the completion.

Example: "deepseek-ai/deepseek-v4-flash-0731"

messagesarray[object]required

A list of messages comprising the conversation so far.

rolestringrequired

The role of the message author. One of "system", "user", or "assistant".

systemuserassistant

contentstringrequired

The content of the message.

temperaturenumber

Controls the variety of the model's responses. Lower values make output more predictable and deterministic, higher values more diverse and random.

Default: 1Min: 0Max: 2

top_pnumber

Nucleus sampling: limits the model's choices to the smallest set of tokens whose cumulative probability reaches top_p. It is recommended to adjust either this or temperature, not both.

Default: 1Min: 0Max: 1

top_kinteger

Limits the model's choice to the k most likely tokens at each step. Set to 0 or omit to disable.

Default: 0Min: 0

min_pnumber

Minimum probability threshold for a token to be considered, measured relative to the probability of the most likely token. Tokens below this threshold are filtered out.

Default: 0Min: 0Max: 1

frequency_penaltynumber

Penalizes tokens based on how frequently they have appeared in the text so far, reducing verbatim repetition. Negative values encourage token reuse.

Default: 0Min: -2Max: 2

presence_penaltynumber

Penalizes tokens that have already appeared in the text regardless of frequency, encouraging the model to introduce new topics.

Default: 0Min: -2Max: 2

repetition_penaltynumber

Multiplicative penalty applied to previously generated tokens. Values greater than 1 discourage repetition; 1 disables it.

Default: 1Min: 0Max: 2

stopstring | array[string]

One or more sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.

seedinteger

Random seed for deterministic sampling. Repeated requests with the same seed and parameters should return the same result.

max_tokensinteger

The maximum number of tokens to generate in the completion. The maximum value is the model's context length minus the prompt length.

Min: 1

logit_biasobject

A map of token IDs to bias values from -100 to 100 that adjust the likelihood of those tokens appearing in the output.

streamboolean

If set to true, partial message deltas will be sent as server-sent events.

Default: false

请求体示例

{
  "model": "deepseek-ai/deepseek-v4-flash-0731",
  "messages": [
    {
      "role": "user",
      "content": "Hello"
    }
  ],
  "max_tokens": 1024,
  "temperature": 0.7,
  "stream": false
}

Output Schema

API 返回兼容 ChatCompletion 的响应格式。

idstringrequired

Unique identifier for the completion.

objectstringrequired

Object type, always "chat.completion".

Default: "chat.completion"

createdintegerrequired

Unix timestamp of when the completion was created.

modelstringrequired

The model used for the completion.

choicesarray[object]required

List of completion choices.

indexintegerrequired

Index of the choice.

messageobjectrequired

The generated message.

finish_reasonstringrequired

The reason generation stopped.

stoplengthcontent_filter

usageobjectrequired

Token usage statistics.

prompt_tokensintegerrequired

Number of tokens in the prompt.

completion_tokensintegerrequired

Number of tokens in the completion.

total_tokensintegerrequired

Total tokens used.
