安裝

安裝所需的相依套件。

pip install requests

驗證

所有 API 請求都需要透過 API Key 進行認證。您可以在 Atlas Cloud 控制台取得 API Key。

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

HTTP 標頭

import os

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

保護好您的 API Key

切勿在客戶端程式碼或公開儲存庫中暴露您的 API Key。請使用環境變數或後端代理。

Input Schema

以下參數在請求主體中被接受。

總計: 14必填: 2選填: 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
