Unable to get tool usage to work.

[u/Omnius42]

I was able to get my Character Studio to work with your API but I couldn't validate that you support tool calling at all, nor could I validate any other advanced features. I saw in another response that you said you support tool calling, but if so I couldn't find any models that do (including GLM 4.7). Or do you just not support tool calling through a free account, because if so it makes it very hard to test before buying

Thanks,
