Can I use a custom module with /<module>/filters?

I'm trying to use the <siteurl>/<module>/filters endpoint. 

I have it working with the following modules:



But it's not working with the module below:


Error I receive:

status code: 404
{"error":"no_method","error_message":"Could not find a route with 2 elements"}


There is a 'PayServiceProviders' in my sugar but I'm not sure if 'PayServiceProviders' is a custom module or not.  I couldn't find a list of default modules that come with sugarcrm to determine that.

If it's a custom module, I'm I able to extract data using the filters endpoint?

Any help is much appreciated, thanks
