Anthropic Format Converter

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

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

cURL / Direct API

For direct API calls, use the full endpoint:

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

Usage Examples

Python SDK
TypeScript SDK
cURL

import anthropic

client = anthropic.Anthropic(
    api_key="your-pipellm-api-key",
    base_url="https://api.pipellm.ai/anthropic"
)

message = client.messages.create(
    model="gemini-2.0-flash",  # or "gpt-4o"
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello, how are you?"}
    ]
)

print(message.content[0].text)

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: "your-pipellm-api-key",
  baseURL: "https://api.pipellm.ai/anthropic",
});

const message = await client.messages.create({
  model: "gemini-2.0-flash", // or 'gpt-4o'
  max_tokens: 1024,
  messages: [{ role: "user", content: "Hello, how are you?" }],
});

console.log(message.content[0].text);

curl https://api.pipellm.ai/anthropic/v1/messages \
  -H "Content-Type: application/json" \
