You might be able to do that with a Multipart input: https://docs.bentoml.org/en/latest/reference/api_io_descriptors.html#multipart-payloads

But isn’t Multipart used when I have multiple inputs at the same time? (eg. dataframe and json) What if I want to have one input at the time, but it can be either json or dataframe, will it still work?

You could try sending both parts, but leave one as empty data for the one you don't need. then just do value checking on the back end? Never tried it, honestly, but it might be worth a shot

Will try it, thank you @Jim Rohrer for the answer!

sure thing!
