Migrating from OpenAI SDK

This guide will help you migrate your existing OpenAI SDK (Python or Node.js) integration to use the AI Stats Gateway instead.

​
Overview

AI Stats Gateway provides OpenAI-compatible endpoints, making migration straightforward. You’ll primarily need to:
  • Change the API base URL
  • Update your API key
  • Update authentication method (from api_key to Authorization: Bearer)

​
Prerequisites

  • An AI Stats account and API key (get one at AI Stats Dashboard)
  • Existing OpenAI SDK code

​
Migration Steps

​
1. Update API Key and Base URL

Instead of using the OpenAI API key and default base URL, use your AI Stats credentials. 
# Before (OpenAI)
curl https://api.openai.com/v1/chat/completions \
  -H "Authorization: Bearer sk-your-openai-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

# After (AI Stats)

curl https://api.phaseo.app/v1/chat/completions \
 -H "Authorization: Bearer your-ai-stats-key" \
 -H "Content-Type: application/json" \
 -d '{
"model": "gpt-4",
"messages": [{"role": "user", "content": "Hello!"}]
}'

​
3. Test Your Integration

Run your existing code with the updated configuration to ensure it works.

​
4. Handle Model Names

AI Stats supports a wide range of models. Check the models endpoint for available models and their names. Some model names may differ from OpenAI’s naming convention.

​
Common Issues

  • Model not found: Ensure the model name is available in AI Stats. Use the /models endpoint to list available models.
  • Rate limits: AI Stats may have different rate limits than OpenAI.
  • Features: Some OpenAI-specific features may not be available or work differently.

​
Next Steps

  • Explore AI Stats’ additional features like analytics and multi-provider routing.
  • Check out the API Reference for full documentation.
