OpenClaw API setup with cheap multi-model access

Setup

1. 1.
   Create a free account and copy your API key.
2. 2.

   Add the provider to ~/.openclaw/openclaw.json while preserving the rest of your existing settings:

   {
     "agents": {
       "defaults": {
         "model": {
           "primary": "9router/gpt-5.6-terra"
         }
       }
     },
     "models": {
       "providers": {
         "9router": {
           "baseUrl": "https://anymodel.org/v1",
           "apiKey": "<YOUR_API_KEY>",
           "api": "openai-completions",
           "models": [
             {
               "id": "gpt-5.6-terra",
               "name": "GPT-5.6 Terra"
             }
           ]
         }
       }
     }
   }

   Restart OpenClaw. To switch models, add another id to the models array and set primary to 9router/<model-id>.

3. 3.
   Start coding. Switch models any time by changing the model id — same key, same endpoint.
