LLM Warehouse

🏠 Auto-capture OpenAI and Anthropic LLM calls for warehousing

A lightweight Python library that automatically logs all your OpenAI and Anthropic API calls to various storage backends, including your own Flask app, Supabase, or local files.

🚀 Quick Start

Installation

pip install llm-warehouse

Or for the latest development version:

pip install git+https://github.com/sinanozdemir/llm-warehouse.git

Basic Usage

For automatic patching on import, set environment variables:

export LLM_WAREHOUSE_API_KEY="your-warehouse-api-key"
export LLM_WAREHOUSE_URL="https://your-warehouse.com"

Then just import any LLM library AFTER importing this package - logging happens automatically:

import llm_warehouse  # BEFORE openai or anthropic

import openai  # Automatically patched!
# or
import anthropic  # Automatically patched!

Sample usage:

import llm_warehouse

# Now use OpenAI/Anthropic normally - all calls are automatically logged!
import openai
client = openai.Client()
response = client.chat.completions.create(
    model="gpt-4.1-mini",
    messages=[{"role": "user", "content": "Hello!"}]
)

📊 What Gets Logged

• Request data: Model, messages, parameters
• Response data: Completions, token usage, timing
• Metadata: Timestamps, SDK method, streaming info
• Errors: API errors and exceptions

🔧 Configuration Options

🛡️ Environment Variables

🔄 Programmatic Control (for advanced users)

import llm_warehouse

# Enable logging
llm_warehouse.patch(warehouse_url="...", api_key="...")

# Disable logging
llm_warehouse.unpatch()

# Check status
if llm_warehouse.is_patched():
    print("LLM calls are being logged")

🏗️ Backend Options
