Setup

  1. Install ToolPiper and launch it once. The local API listens on port 9998.
  2. Create a Developer Token on the ToolPiper API page. Every request to the local API carries one.
  3. Point aider at the local endpoint.
export OPENAI_API_BASE=http://localhost:9998/v1
export OPENAI_API_KEY=tp_YOUR_TOKEN   # a Developer Token from the ToolPiper API page
aider --model openai/qwen3.8-27b

Prompts, responses and files stay on the machine. There is no key to rotate and no per-token cost. aider talks to ToolPiper over its local OpenAI-compatible API on port 9998.
