How to Retrieve Field Metadata for List Object?

Hi,

I am working on SharePoint 2013 Integration, in which I am working on List, List Item Objects.

List API’s support ‘Custom Fields’ creation. From the REST API the custom fields gets created in an application by using /Field API. But, while retrieving the metadata of fields from already created lists usingGET /Fields, we are not getting proper metadata for complex structures eg. uri and GeoLocation like fields and other complex elements. 
The same problem exists in case of standard fields and for custom field of List having complex structures. 

Can you please let us know if there is an API to retrieve the complete metadata of fields for List?

Thanks.
