Create JSON API

[miron]

• You can do websockets in Flask too: Flask SocketIO

• Flasks own request instance of Request class and requests

• Rewrite of cmd to client that gets data from API endpoints instead of importing Algo class.

• API documentation in get request at root, i.e. api.street.yoga/
  Returns all endpoints and servertime from class, but split it up to appropriate resource classes and save to database.
  check postman Code snippets for http.client or requests payload
  See this list of http-clients, it includes asynchronious libraries and even one that offers HTTP 2.0 support.
  Using one of the asynchronious ones is a strong consideration.

• Websockets under Windows: pyOpenSSL expects trusted root set from twisted but gets none:

  In PowerShell:

  Can't run any websocket example binance/binance-connector-python#57 (comment)

  PS C:\> $env:SSL_CERT_FILE=(py -m certifi); py yourscript.py

  In Script:

  Can't run any websocket example binance/binance-connector-python#57 (comment)

  import os, certifi, win32api
  from binance.websocket.spot.websocket_client \
      import SpotWebsocketClient as WebsocketClient
  os.environ['SSL_CERT_FILE'] = certifi.where()
  ws_client = WebsocketClient()
  
  def message_handler(message):
      print(message)
  
  ws_client.start()
  
  ws_client.mini_ticker(
      symbol='bnbusdt',
      id=1,
     callback=message_handler,
  )
  
  # Combine selected streams
  ws_client.instant_subscribe(
     stream=['bnbusdt@bookTicker', 'ethusdt@bookTicker'],
      callback=message_handler,
  )
  
  win32api.SetConsoleCtrlHandler(lambda _: ws_client.stop(), True)

  Cryptographic Authority wants to kill pyopenssl, avoid, as well as frameworks that depend on it, like twisted

• An alternative to Flask is FastAPI, uses asyncio

• Removed binance-connector because being dependant on twisted

• Pyramid and Django probably overkill
