v2.7: Update apiUrl and pass on API errors to client SDK
This update comes with the following changes:
- All requests are now forwarded to the new API endpoint, i.e.
api.cryptolens.io
. - The content type that is returned is now the same as the one from the API, i.e.
application/json
. - In case of an error (400 or 500) from the API, it will be passed on to the client library.
