Using TOKENOPEN API with OpenClaw

OpenClaw is an open-source AI coding agent. It can autonomously read files, write code, execute commands, and complete complex development tasks. By configuring TOKENOPEN API, you can use all models available on the platform.

OpenClaw requires Node.js 22+. Please ensure Node.js is installed before proceeding.

Step 1: Install OpenClaw

Use the official install script:

curl -fsSL https://install.openclaw.dev | bash

Verify the installation:

openclaw --version

Run in PowerShell:

iex (irm https://install.openclaw.dev/windows)

Verify the installation:

openclaw --version

Step 2: Configure TOKENOPEN API

Get an API Key

(Optional) Install System Daemon

If you want OpenClaw to run persistently as a background service, run:

openclaw onboard --install-daemon

Edit the Configuration File

OpenClaw's configuration file is located at ~/.openclaw/openclaw.json. Open and edit it:

mkdir -p ~/.openclaw
vim ~/.openclaw/openclaw.json

Paste or Modify the following content:

{
  "models": {
    "mode": "merge",
    "providers": {
      "custom-proxy": {
        "baseUrl": "https://www.tokenopen.ai/v1",
        "apiKey": "replace-with-your-api-key",
        "api": "openai-completions",
        "auth": "api-key",
        "models": [
          {
            "id": "replace-with-model-id",

      }
    }
  }
}

Reference options:

Parameter	Example value	Notes
`models[].id`	`gpt-5.5` or `claude-sonnet-4-6`	Set the actual model ID to call, matching a model identifier supported by TOKENOPEN
`agents.defaults.model.primary`	`custom-proxy/gpt-5.5` or `custom-proxy/claude-sonnet-4-6`	Set this to the primary model ID or Name you want to use

Press Esc, then type :wq! to save and quit.
