apicrusher 2.2.1

Cut AI API costs by 63-99% with intelligent routing across all AI providers

APICrusher - Cut AI API Costs by 63-99%

Stop bleeding money on AI APIs. APICrusher automatically routes requests to the cheapest capable model and caches responses, cutting costs by 63-99% with just 2 lines of code.

🚀 Quick Start

# Python 3.7+ required
# Use a virtual environment (recommended for all Python packages)
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install with your provider(s)
pip install apicrusher[standard]  # OpenAI + Redis caching (recommended)
# OR
pip install apicrusher[all]       # All providers (OpenAI, Anthropic, Google, etc.)

📋 Installation Options

# Choose based on your needs:
pip install apicrusher[standard]   # OpenAI + Redis (most users)
pip install apicrusher[openai]     # Just OpenAI support
pip install apicrusher[anthropic]  # Just Anthropic support
pip install apicrusher[google]     # Just Google support
pip install apicrusher[all]        # Everything - all providers
pip install apicrusher              # Minimal - add providers later

Virtual Environment Required

Modern Python systems require virtual environments for pip packages:

# If you see "externally-managed-environment" error:
python3 -m venv venv
source venv/bin/activate
pip install apicrusher[standard]

API Keys Required

APICrusher optimizes your existing AI API calls. You need:

1. Your AI provider API key (OpenAI, Anthropic, etc.) - Keep using your existing keys
2. An APICrusher optimization key from apicrusher.com - Enables cost optimization

How It Works

APICrusher is a smart proxy layer. You keep your existing API keys. We analyze each request and route it to the optimal model. Your API keys never leave your server.

💻 Basic Usage

# Before (expensive)
from openai import OpenAI
client = OpenAI(api_key="sk-...")  # Your OpenAI key

# After (63-99% cheaper)
from apicrusher import OpenAI
client = OpenAI(
    openai_api_key="sk-...",        # Your existing OpenAI key
    apicrusher_key="apc_live_..."   # Add optimization key
)

# Your code stays exactly the same
response = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Hello!"}]
)

💰 How Much Can You Save?

Single Provider vs Cross-Provider

• Single Provider (e.g., just OpenAI): 70-85% savings
• Cross-Provider (e.g., OpenAI + Anthropic): Up to 99% savings

Your Current Usage	Monthly Cost	With APICrusher	You Save
GPT-4 for everything	$1,000	$180	$820 (82%)
Mixed GPT-4/3.5	$500	$95	$405 (81%)
Heavy API usage	$5,000	$750	$4,250 (85%)
Long conversations	$2,000	$340	$1,660 (83%)

🎯 Core Features

Cross-Provider Optimization (NEW in v2.0)

Get 99% savings by routing between providers:

from apicrusher import OpenAI

client = OpenAI(
    openai_api_key="sk-...",             # Your OpenAI key
    anthropic_api_key="sk-ant-...",      # Optional: Add for 99% savings
    google_api_key="...",                # Optional: Add Google key
    apicrusher_key="apc_live_..."    
)

# Simple GPT-4 queries now route to Claude Haiku automatically (99% cheaper)
# Complex queries stay on GPT-4 to preserve quality

Universal Provider Support

Works with ALL major AI providers and models:

• OpenAI: GPT-5, GPT-4, GPT-4o, O1, O3 (all current models)
• Anthropic: Claude Opus 4.1, Claude Sonnet 4, Claude 3.5
• Google: Gemini 2.0, Gemini 1.5 Pro/Flash
• Meta: Llama 3.3, Llama 3.2, Code Llama
• Others: Groq, Cohere, Mistral, DeepSeek, and more

Intelligent Model Routing

• Simple queries → Cheap models (gpt-4o-mini)
• Complex queries → Premium models (GPT-5, Claude Opus 4.1)
• Automatic quality preservation

Smart Caching

• Deduplicates identical requests
• Redis + in-memory fallback
• 33% average cache hit rate

🆕 Context Compression (NEW!)

Stop paying to reprocess the same conversation 50 times:

# Enable context compression for long conversations
response = client.chat.completions.create(
    model="gpt-4",
    messages=conversation_history,  # 50 messages = 15,000 tokens normally
    compress_context=True  # Reduces to ~3,000 tokens automatically
)

# Features:
# - Summarizes older messages while preserving key decisions
# - Removes duplicate context automatically  
# - Compresses code blocks by 40-60%
# - Sends only deltas for continuing conversations
# - Preserves last 3 messages in full for accuracy

Context Compression Savings Example:

• Normal 20-message conversation: 150,000 tokens ($2.25)
• With compression: 35,000 tokens ($0.52)
• Savings: 77% on long conversations
