# Migrating from Helicone AI Gateway

This guide helps migrate from Helicone's gateway to AI Stats.

## Overview

Both provide AI API proxying with observability. Migration involves:

* Changing base URL
* Updating authentication
* Adjusting configuration

## Prerequisites

* AI Stats account
* Helicone setup

## Migration Steps

### 1. Update Base URL

Replace Helicone's proxy URL.

<CodeGroup>
  ```bash theme={null}
  # Before (Helicone proxy)
  curl https://oai.helicone.ai/v1/chat/completions \
    -H "Authorization: Bearer sk-your-openai-key" \
    -H "Helicone-Auth: Bearer your-helicone-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!"}]
  }'

  ```

  ```python theme={null}
  import openai

  client = openai.OpenAI(
      api_key="your-ai-stats-key",
      base_url="https://api.phaseo.app/v1"
  )

  response = client.chat.completions.create(
      model="gpt-4",
      messages=[{"role": "user", "content": "Hello!"}]
  )
  ```

  ```javascript theme={null}
  import OpenAI from "openai";

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

  const response = await client.chat.completions.create({
  	model: "gpt-4",
  	messages: [{ role: "user", content: "Hello!" }],
  });
  ```
</CodeGroup>

### 2. Authentication

Use Bearer token.

Remove Helicone-specific headers.

### 3. Observability

AI Stats provides analytics. Migrate monitoring accordingly.

### 4. Test

Ensure requests work.

## Common Issues

* **Headers**: Remove Helicone-specific headers.
* **Logging**: Different observability features.

## Next Steps

* Set up AI Stats analytics.
