I would like to retrieve my account credits via the API so that I can render them on my interface. Currently I must make a request (any request) in order to read the headers outlined in the docs
https://graphhopper.com/api/1/docs/#http-headers
However, I want to use a request that doesn’t have a cost, ie: /api/v1/usage?key=abc123
Is that currently possible, or will it need to be added?
