OpenClaw is an extremely popular open-source command-line AI coding agent. It aims to provide capabilities similar to Claude Code while remaining fully open-source and supporting custom API access.

​
Installation

Make sure you have Python 3.10+ installed: 
pip install openclaw

​
Configuration & Launch

OpenClaw can be configured via environment variables or an interactive setup. 
echo 'export OPENAI_API_KEY="sk-your-api-key"' >> ~/.zshrc
echo 'export OPENAI_API_BASE="https://api.ephone.ai/v1"' >> ~/.zshrc
source ~/.zshrc

[Environment]::SetEnvironmentVariable("OPENAI_API_KEY", "sk-your-api-key", "User")
[Environment]::SetEnvironmentVariable("OPENAI_API_BASE", "https://api.ephone.ai/v1", "User")

​
Option 2: Interactive Setup

Run openclaw directly, and the program will guide you through the API configuration:
  1. API Key: Enter your ePhone AI API Key
  2. Base URL: Enter https://api.ephone.ai/v1
  3. Model: Recommended gpt-4o or claude-opus-4-5-20251101

As a powerful agent, OpenClaw performs significant context reading and model calls, leading to faster token consumption. We recommend using a Tier 2 account for a more stable experience.
