**Is your feature request related to a problem? Please describe.** I would like to make requests without the full URL. **Describe the solution you'd like** I'd like to define a class or instance attribute `base_url` that is automatically prepended to the endpoint passed into `get`, `post`, etc. **Describe alternatives you've considered** Considering subclassing, but it feels like this is a fundamental feature. Did I miss it in the documentation?
