arato-proxy 0.1.0

LiteLLM proxy for Arato logs

LiteLLM based proxy for Arato Logs

Use this LiteLLM proxy to send logs data to an Arato monitoring endpoint. All LLM calls going through the proxy will be logged in Arato.

Quick Start

Using uvx (Recommended)

Since this package is not yet published to PyPI, you can use uvx with the local wheel:

# First, build the package
uv build

# Run directly without installation using the local wheel
uvx --from ./dist/arato_proxy-*.whl arato-proxy

# Or with custom configuration
uvx --from ./dist/arato_proxy-*.whl arato-proxy --config custom.yaml --port 8080

Using uv/pip (Development Install)

# Install from source in development mode
uv pip install -e .

# Or install from the built wheel
uv pip install ./dist/arato_proxy-*.whl

# Then run
arato-proxy

Publishing to PyPI (For Maintainers)

To publish a new version to PyPI:

# Create and push a new version tag
git tag v0.1.1
git push origin v0.1.1

# Create a GitHub release from the tag
# This will automatically trigger the GitHub Actions workflow to publish to PyPI

The GitHub Actions workflow will:

1. Extract the version from the git tag (removing 'v' prefix if present)
2. Update the version in pyproject.toml
3. Build the package
4. Publish to PyPI using trusted publishing

Once published to PyPI, users will be able to run:

# After publishing to PyPI
uvx arato-proxy
pip install arato-proxy

GitHub Actions

This repository includes automated workflows:

• Test: Runs tests on Python 3.8-3.12 for all PRs and pushes
• Release: Automatically publishes to PyPI when a GitHub release is created
  • Version is automatically extracted from the git tag
  • No manual version management needed

Setup

Environment Variables

You need to setup environment variables with the following keys:

OPENAI_API_KEY="sk-..."
ARATO_API_URL="https://api.arato.ai/..."
ARATO_API_KEY="ar-..."

You can create a .env file or set them in your environment:

# Generate template .env file
arato-proxy --init-env

Configuration

The proxy uses a YAML configuration file (config.yaml). You can generate a template:

# Generate template config.yaml
arato-proxy --init-config

CLI Usage

The arato-proxy command provides several options:

# Show help
arato-proxy --help

# Start with default settings
arato-proxy

# Start with custom configuration
arato-proxy --config custom.yaml --port 8080

# Generate template files
arato-proxy --init-config    # Creates config.yaml
arato-proxy --init-env       # Creates .env

Known Issue: Callback Loading

Currently, the Arato callback functionality has a compatibility issue when running via uvx. The proxy will start and work with basic LiteLLM functionality, but the Arato-specific logging callbacks may not load properly in packaged environments. This is being investigated.

For now, you can use the proxy for basic LiteLLM functionality, and the callback issue will be resolved in a future update.

Required Environment Variables

• ARATO_API_URL - URL of the Arato API endpoint
• ARATO_API_KEY - API key for authentication
• OPENAI_API_KEY - OpenAI API key for the proxy

Development

From Source

git clone https://github.com/AratoAi/litellm-proxy
cd litellm
python3 -m venv .venv
source .venv/bin/activate
uv pip install -e .

Running Tests

python -m pytest test_custom_callbacks.py -v

Building the Package

uv build

Installing in Development Mode

uv pip install -e .

Example usage with n8n

In n8n, create a new OpenAI integration and set the base URL to point to your LiteLLM endpoint
