System description

The system allows to make currency conversion requests. For each request, the users specifies the source currency, the target currency and the amount they want to convert.

The system must validate data for invalid values, such as malformed currency code, negative amounts.

Whenever a request for a not existing currency is done, the system must return an error messsage and the administrator must be notified via email.

Any request done in the morning (A.M. hours) must be rejected.

It should be possible to use both database and api calls to http REST service as conversion source. The conversion source could be optionally cached.

When using a database, a CSV file containing data could be imported to feed the table. Such functionality can be used from both an http endpoint and a console command
