Anthropic API Key
OpenClaw needs an API key to communicate with Claude.
1. Create an Anthropic account
Go to console.anthropic.com and create an account.
2. Generate an API key
Go to Settings → API Keys, then click “Create Key”. Give it a name (e.g. “OpenClaw”).
The key starts with sk-ant-. Copy it immediately — you won’t be able to see it again after.
3. Add credits
Go to Billing and add $10 minimum. You only pay for what you use.
💡 $10 is plenty for several weeks of normal usage.
Other providers (optional)
OpenClaw also supports OpenAI and Google Gemini:
