Install

Install the required package for your language.

pip install requests

Authentication

All API requests require authentication via an API key. You can get your API key from the Atlas Cloud dashboard.

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

HTTP Headers

import os

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

Keep your API key secure

Never expose your API key in client-side code or public repositories. Use environment variables or a backend proxy instead.

Submit a request

import requests

url = "https://api.atlascloud.ai/v1/chat/completions"
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer $ATLASCLOUD_API_KEY"
}
data = {
    "model": "deepseek-ai/deepseek-v4-flash-vision-exp",
    "messages": [
        {
            "role": "user",
            "content": "what is difference between http and https"
        }
    ],
    "max_tokens": 32768,
    "temperature": 0.7,
    "stream": False
}

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

Input Schema

The following parameters are accepted in the request body.

Total: 14Required: 2Optional: 12

modelstringrequired

The model ID to use for the completion.

Example: "deepseek-ai/deepseek-v4-flash-vision-exp"

messagesarray[object]required

A list of messages comprising the conversation so far.

rolestringrequired

The role of the message author.

systemuserassistant

contentstring | array[object]required

Plain text, or an array of content parts for multimodal input. Combine a media part with a text part to ask a question about the media. Accepts image (png, jpeg, webp, gif).

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
