How to config Endpoint of LLM?

[Wedo201511]

Hi, thanks for open-sourcing this project.

I checked the README and found the API key environment variables (OPENAI_API_KEY, ANTHROPIC_API_KEY, GEMINI_API_KEY, etc.), but I couldn't find any documentation for configuring a custom API endpoint / base URL for the LLM provider.

Is there currently a supported way to set a custom endpoint, for example for Azure OpenAI or another OpenAI-compatible API?

If yes, could you point me to the relevant configuration or example?
If not, does the current implementation assume the default provider endpoints only?

I may have overlooked it, so I wanted to ask here. Thanks!
