Migrating from Vercel AI Gateway

This guide will help you migrate from Vercel’s AI Gateway to AI Stats Gateway.

​
Overview

Both Vercel AI Gateway and AI Stats provide unified access to multiple AI providers. Migration involves:
  • Updating API endpoints
  • Changing authentication
  • Adjusting configuration

​
Prerequisites

  • AI Stats account and API key
  • Existing Vercel AI Gateway setup

​
Migration Steps

​
1. Update Base URL

Replace Vercel’s gateway URL with AI Stats’. 
# Before (Vercel AI Gateway)
curl https://your-gateway.vercel.ai/v1/chat/completions \
  -H "Authorization: Bearer your-vercel-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!"}]
}'

​
2. Update Authentication

Use Bearer token instead of Vercel’s auth method.

​
3. Model Configuration

Vercel AI Gateway routes based on model names. AI Stats uses similar routing. Check available models via /models endpoint.

​
4. Test Integration

Verify your applications work with the new gateway.

​
Common Issues

  • Routing differences: Model availability may vary.
  • Caching: Vercel’s caching behavior may differ.
