Point it at idapt
bash
# n8n > Credentials > New > OpenAI
API Key: <IDAPT_API_KEY>
Base URL: https://idapt.app/api/openai/v1
# Then in the OpenAI / Basic LLM Chain node:
Model: minimax/minimax-m3The Base URL field lives under the credential's options; nodes using that credential inherit it.
Pitfalls
Type the model id, do not pick from the dropdown
n8n's model dropdown lists OpenAI names only. Switch the field to expression/plain input and type the catalog id.
