Get started with the API

AI Studio exposes an OpenAI-compatible API for inference, image generation, fine-tuning, and more. Create a key, make your first request, then explore the full API reference.

Before you begin

You'll need:

1. A Hyperstack account. Sign up on the registration page using your email or an SSO provider (Google, Microsoft, or GitHub).
2. Billing set up. Add credit to your account.
3. Access to AI Studio. Open AI Studio in the Hyperstack console.

Create a key and make your first request

1. Create an API key

   Navigate to the API Keys page under Manage. Click Generate new API key, name it, and confirm. Copy the key right away, since it is shown only once.

2. Make your first request

   Call the chat completions endpoint, replacing API_KEY with your key:

   terminal

   curl -X POST "https://console.hyperstack.cloud/ai/api/v1/chat/completions" \
   -H "Content-Type: application/json" \
   -H "api_key: API_KEY" \
   -d '{
     "model": "mistralai/Mistral-Small-24B-Instruct-2501",
     "messages": [
       {"role": "user", "content": "Hello"}
     ],
     "stream": true
   }'

   A streamed completion confirms your key works. The API follows the OpenAI format, so existing OpenAI SDKs and tools work once you point them at the AI Studio base URL.

What's next

Once you're authenticated, these are the main things you can do with the API. Each card links to the relevant section of the API reference:

Run inference

Send chat completion requests to any base or fine-tuned model.

Generate images

Create images from a text prompt, or edit an existing image.

AI Studio API reference

Overview

Browse the full AI Studio documentation.

Fine-tuning a model

Fine-tuning is a multi-step workflow that uploads training data, starts a job, and deploys the result, so the simplest path is the console UI. Follow the Fine-tune a model guide. To do it programmatically, see the Fine-tuning section of the API reference.
