# 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
```bash
# 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
```bash
# 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:
```bash
# 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](https://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
```python
# 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:
```python
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:**
```python
# 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**
