Open Router - Config.toml

[esfolk]

I want to use Open Router API key with codex.

I added the following below

*model_provider = "openrouter"

[model_providers.openrouter]
name = "OpenRouter"
base_url = "https://openrouter.ai/api/v1"
env_key = "OPENROUTER_API_KEY"
wire_api = "chat"*

When I try to use Codex - it does not register the connection. I am on Chatgpt Free plan
