Migrate from Anthropic to ParrotRouter

Keep using Claude while gaining access to 100+ additional models. Seamless migration with enhanced reliability and cost savings.

Python SDK Migration

Before (Anthropic SDK):

import anthropic

client = anthropic.Anthropic(
    api_key="sk-ant-..."
)

response = client.messages.create(
    model="claude-3-opus-20240229",
    messages=[{"role": "user", "content": "Hello!"}],
    max_tokens=1000
)

After (ParrotRouter):

from openai import OpenAI  # Use OpenAI SDK

client = OpenAI(
    api_key="YOUR_PARROTROUTER_KEY",
    base_url="https://api.parrotrouter.com/v1"
)

response = client.chat.completions.create(
    model="claude-3-opus-20240229",  # Same model!
    messages=[{"role": "user", "content": "Hello!"}],
    max_tokens=1000
)

Pro tip: ParrotRouter supports both Anthropic's message format and OpenAI's chat format, making migration even easier.
