Migrate from OpenAI

Migrating from the OpenAI API to TokenSupernova requires exactly two changes in your code.

Step 1: Change the Base URL

base_url="https://api.openai.com/v1"
base_url="https://api.tokensupernova.com/v1"

Step 2: Change the API Key

api_key="sk-proj-xxxxxxxxxxxxx"
api_key="tsn_live_xxxxxxxxxxxxx"

That’s It

Your existing code continues to work. All standard OpenAI parameters (temperature, max_tokens, stream, etc.) are supported.

Language-Specific Examples

:::tab Python

# Before (OpenAI)
from openai import OpenAI
client = OpenAI(
    api_key="sk-proj-xxx",
)

# After (TokenSupernova)
from openai import OpenAI
client = OpenAI(
    api_key="tsn_live_xxx",
    base_url="https://api.tokensupernova.com/v1",
)

:::tab Node.js

// Before (OpenAI)
import OpenAI from "openai";
const client = new OpenAI({
  apiKey: "sk-proj-xxx",
});

// After (TokenSupernova)
import OpenAI from "openai";
const client = new OpenAI({
  apiKey: "tsn_live_xxx",
  baseURL: "https://api.tokensupernova.com/v1",
});

Model Mapping

OpenAI Model	TokenSupernova Equivalent	Notes
gpt-4o	deepseek-chat	Strong general performance
gpt-4o-mini	qwen-plus	Budget-friendly, fast
o1 / o3	deepseek-reasoner	Reasoning tasks

Environment Variable Setup

Store credentials in environment variables for easy switching:

.env

OPENAI_API_KEY=tsn_live_xxx
OPENAI_BASE_URL=https://api.tokensupernova.com/v1

Then use the default client:

from openai import OpenAI
client = OpenAI()  # Reads OPENAI_API_KEY and OPENAI_BASE_URL from env

Things to Know
