OpenRouter Support

[Pertempto]

It would be great if Chef had support for OpenRouter API keys. I prefer to use OpenRouter for easy management rather than get my API keys from all the different providers.

UP, I also want this feature to support API Compatible OpenAI like Openrouter and https://agentrouter.org/

This can be done by changing the OpenAI URL from openai to service with same API type as OpenAI

I didn't see a way to do this from the UI. How can I configure this?

Suggested starting point:
I was looking at enabling ChatGPT 5 (haven't tried yet) and wanted to use OpenRouter -- found the API request URL here: "convex/openaiProxy.ts", see line 90 copied below. You'd change the base URL to "https://openrouter.ai/api/v1" from ""https://api.openai.com/v1/". The URL is also in "convex/apiKeys.ts", I believe this is a function that validates keys, haven't looked too closely but you'd want to update URL there too if using OpenRouter API key.

A more elegant way would be to add an environment variable: ${process.env.OPENAI_BASE_URL} then make sure you define "OPENAI_BASE_URL" in your .env.local file.

Existing code from 'convex/openaiProxy.ts':

const response = await fetch("https://api.openai.com/v1/chat/completions", {
method: "POST",
headers: {
"Content-Type": "application/json",
Authorization: Bearer ${process.env.OPENAI_API_KEY},
},
body: JSON.stringify(proxiedBody),
});
return response;
