Before you start, install the tool and create an API key with prepaid balance in the AsterWise app.
Based on the tool’s documented custom-provider setup. Live AsterWise compatibility has not yet been tested for this tool.

​
Which API does this use?

This guide selects Chat Completions through the openai/ adapter. The base URL is https://api.asterwise.dev/v1. The client builds the full endpoint: https://api.asterwise.dev/v1/chat/completions. The model name chooses AsterCode or AsterWork, not the protocol. Use the base URL in the configuration below, rather than the full endpoint.

​
1. Set the endpoint and key

In a terminal, replace the placeholder with your AsterWise key:
Aider uses OPENAI_API_BASE here, rather than OPENAI_BASE_URL.

​
2. Start Aider in your project

Change into your project directory, then run:
The openai/ prefix selects Aider’s API adapter. The model sent to AsterWise is aster-code. Use openai/aster-work to select AsterWork. If Aider warns that a custom model is unknown, review its model settings; do not treat inferred context limits or cost estimates as authoritative. Check actual charges in AsterWise Usage.

​
Check the connection

Ask “Reply with hello” first. Confirm a response appears and find the request in Usage in AsterWise. Then try a small coding task before a larger project. For authentication errors, check the key and restart the tool from the terminal where you exported it. See troubleshooting.
