Step 4: Make Your First API Call

Chat with an LLM

Atlas Cloud's LLM API is fully OpenAI-compatible. If you're already using the OpenAI SDK, just change the base URL and API key.

from openai import OpenAI

client = OpenAI(
    api_key="your-api-key",
    base_url="https://api.atlascloud.ai/v1"
)

response = client.chat.completions.create(
    model="deepseek-v3",
    messages=[
        {"role": "user", "content": "Hello! What can you do?"}
    ]
)

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

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "your-api-key",
  baseURL: "https://api.atlascloud.ai/v1",
});

const response = await client.chat.completions.create({
  model: "deepseek-v3",
  messages: [{ role: "user", content: "Hello! What can you do?" }],
});

console.log(response.choices[0].message.content);

curl https://api.atlascloud.ai/v1/chat/completions \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-v3",
    "messages": [
      {"role": "user", "content": "Hello! What can you do?"}
    ]
  }'

Generate an Image

curl -X POST https://api.atlascloud.ai/api/v1/model/generateImage \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-3.0",
    "prompt": "A beautiful sunset over snow-capped mountains, photorealistic"
  }'

Generate a Video

curl -X POST https://api.atlascloud.ai/api/v1/model/generateVideo \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kling-v2.0",
    "prompt": "A rocket launching into space with dramatic lighting"
  }'

Upload Media

Upload local files to get temporary URLs for image-to-video, image editing, and other workflows:

curl -X POST https://api.atlascloud.ai/api/v1/model/uploadMedia \
  -H "Authorization: Bearer your-api-key" \
  -F "[email protected]"

Get Generation Result

Image and video generation tasks are asynchronous. Use the prediction ID returned from the generation request to check the status and retrieve results:

curl https://api.atlascloud.ai/api/v1/model/getResult?predictionId=your-prediction-id \
  -H "Authorization: Bearer your-api-key"

Step 5: Explore Models

Browse all 300+ available models on the Model Library to find the right model for your use case. Each model page includes:

Interactive playground for testing
