Unable to set OpenRouter.ai as provider

[GratefulDave]

Issue

I'm trying to set an api token with aider.

Python 3.13.1
Poetry 1.8.5
Aider 0.70.0

Install

Using Pycharm Plugin:
python -m pip install aider-install aider-install
``
% pipx install --python python3.12 aider-
chat
Fatal error from pip prevented installation. Full pip output in file:
/Users/{my_username}/.local/pipx/logs/cmd_2025-01-03_11.33.20_pip_errors.log

Some possibly relevant errors from pip install:
ModuleNotFoundError: No module named 'distutils'

Error installing aider-chat.
``

Steps to reproduce

1. OpenRouter API key works with curl.

2. Tried custom configuration file (.aider.conf.yml):

• openrouter_api_key: {api_key}
• model: deepseek/deepseek-chat (and others)

Error: aider: error: unrecognized arguments: --openrouter_api_key {api_key}

3. Tried .env:

• OPENROUTER_API_KEY: {api_key}
• OPENROUTER_BASE_URL: https://openrouter.ai/api/v1
• MODEL=deepseek/deepseek-chat

Tried all variations of aider_api_key, aider_base_url, api_base/api_url.

All errors are unrecognized arg.

ERROR:

aider: error: unreocgnized arguments .... permutation above.

### Version and model info

Aider version 0.70.0
Model OpenRouter: deepseek/deepseek-chat (and others)
