Parameters

Code Example
import os
from openai import OpenAI

# Multimodal Understanding Example
# Image: use base64 encoding (data:image/png;base64,...) or a public URL

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

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": "openai/gpt-5.5",
    "messages": [
        {
            "role": "user",
            "content": "what is difference between http and https"
        }
    ],
    "max_tokens": 64000,
    "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: 5Required: 2Optional: 3

modelstringrequired

The model ID to use for the completion.

Example: "openai/gpt-5.5"

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).

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

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

streamboolean

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

Default: false
