I want to add information to my each model (Json type or other one)

I am going to add detail information to each model in my sketchfab account.
But couldn’t find the data pool to set.
should I use the category to impletement this?
If there is any function I want to know about that.
Detail information has to be detailed as well.
so I prefer JSON type.

We do not have an option to enrich your models with custom data like that, sorry.

Thanks for your reply.
I think, It might be necessary after this.
Because developers using api can use that data pool to recognize the model or use the model without parsing.
Anyway, thanks for your support.
If you have any idea to implement that function on your platform please let me know.
Thanks again.
