Install OpenClaw manually step by step
Step 1: Install official OpenClaw
Windows PowerShell:
iwr -useb https://openclaw.ai/install.ps1 | iex
macOS/Linux:
curl -fsSL --proto '=https' --tlsv1.2 https://openclaw.ai/install.sh | bash

Windows PowerShell:
$key = Read-Host "SHOP AI PRO API key"
[Environment]::SetEnvironmentVariable("SHOPAI_API_KEY", $key, "User")
$env:SHOPAI_API_KEY = $keymacOS/Linux: create files ~/.openclaw/.env, set permissions
SHOPAI_API_KEY=API_KEY_CUA_BAN
chmod 700 ~/.openclaw chmod 600 ~/.openclaw/.env
Step 3: Get the list of models authorized by the API key
On Windows PowerShell:
$headers = @{ Authorization = "Bearer $env:SHOPAI_API_KEY" }
$result = Invoke-RestMethod -Uri "https://contact.shopaipro.tech/api/v1/usage/models" -Headers $headers -Method Post
$result.models.idStep 4: Initialize OpenClaw
