Describe the enhancement you want to request

This is an API aggregation platform, similar to AIHubMix, and it is very useful to me.

Its OpenAI general interface is: https://www.dmxapi.cn/v1/chat/completions

Its OpenAI responses interface is: https://www.dmxapi.cn/v1/responses

Its Gemini interface is: https://www.dmxapi.cn/v1beta/models/{model}:generateContent?key={API_KEY}

Its Claude interface is: https://www.dmxapi.cn/v1/messages

Its official website is: https://www.dmxapi.cn

I hope this service provider can be added. Thank you very much.
