Deribit Client and a custom API

Overview

The app provides a client to make requests to Deribit API and save the recieved responses into a database. Moreover there is a custom API that reads from the same database and provides three routes.

1. /currency-all-info: provides all the historical data of a specific currency that exist in the database. The name of the currency is passed to the route under the parameter 'ticker_name'.
2. /currency-price: provides the price of a specific currency. The name of the currency is passed to the route under the parameter 'ticker_name'.
3. /currency-by-date: provides all the historical data of a specific currency on a specific date. The name of the currency is passed to the route under the parameter 'ticker_name' and the date is passed under the parameter 'dt', the format of the date argument must be %Y-%m-%d.

The last component of the app is a CLI that provides three main commands.

1. createdb: creates a database at the very first time starting the app, otherwise it returns that there is a database exists.
2. call_deribit: Starts a scheduler that sends requests to Deribit API every minute.
3. run_api: Starts the custom API app.
