Regarding exposing unstructured document loader and langchain FAISS text splitter

[pustakkosh]

Hi,

Thank you for a much needed help on exposing langchain as apis. I dont use python but need to experiment with functionalities like document load using unstructured and FAISS both I think are used in Index module. Could you please provide some documentation example or a hint if its possible to implement some custom say post api which takes as an example a json or string input executes custom langchain functionalities and returns output. Would importing the functions in a custom function and putting them with the decorator be enough? Thanks again for this repository.

Thanks
