Start and endate

Hello I am writing a python program and I want to back test and get historical data on the 1 minute chart. If I could get the format example for this it would be appreciated. Is there also a limit as to how many data points I could test my data on? Thanks.

It’s able to fetch historical klines records from GET /api/v3/klines. For the request limit, please find the details from the API document.
