# Anthropic Format Converter

> Use Gemini and OpenAI models with Anthropic SDK

## Overview

The Anthropic Format Converter allows you to call **Gemini** and **OpenAI** models using the Anthropic SDK and API format. This is useful when you have existing code using the Anthropic SDK but want to access other providers' models.

## Configuration

### SDK Configuration

Set your base URL to:

```
https://api.pipellm.ai/anthropic
```

<Note>
  The SDK automatically appends `/v1/messages`, so you only need to set the base
  URL to `/anthropic`.
</Note>

### cURL / Direct API

For direct API calls, use the full endpoint:

```
https://api.pipellm.ai/anthropic/v1/messages
```
