3.4 OpenClaw

OpenClaw uses the Anthropic protocol. The Base URL must not include /v1.

Two Things to Prepare

Setting	Value
Base URL	https://axiomcode.top (without /v1)
API Key	sk-axiom-YourKey

System requirements

• Node.js 18 or later
• OS: Windows 10/11 · macOS · Linux (major distros)
• Network access to axiomcode.top

Local Installation

npm install -g openclaw
openclaw --version  # verify: printing a version number means it installed

Config file location:

• Linux / macOS: ~/.openclaw/config.yaml
• Windows: %USERPROFILE%\.openclaw\config.yaml

provider:
  type: anthropic
  base_url: https://axiomcode.top
  api_key: sk-axiom-YourKey

model:
  default: claude-sonnet-4-6

Start:

openclaw

Web / Cloud Deployment

When using the hosted version of OpenClaw, go to Settings → Provider to configure:

1. Select "Anthropic Compatible" as the Provider type.
2. Set the Base URL to https://axiomcode.top.
3. Set the API Key to a key starting with sk-axiom-.
4. Test the connection; a response of 200 OK / Connected means success.

Troubleshooting

Symptom	Resolution
401	Check the Key; copy it directly from the console to avoid stray spaces
404	Confirm the Base URL does not include /v1
Abnormal speed	AxiomCode is already optimized for China; adding an extra proxy on top may actually slow things down, so try disabling it
