OData API URL must be basic, but why?

Hi everyone,

i wanted to use my Datas from OData, but we can only enter Base API URL, for example: (https://example/1/odata/v1/), but i need more specific Datas like (https://example/1/odata/v1Tanks/TankVolumes). If i enter this URL, i get this message, “The entered URL is not recognized as a valid OData service metadata”.
What can i do? Thanks.
