i am also facing same issue

I am new to working with API
yesterday my code was working fine. but oday i got a error
"Historic Api failed: Couldn't parse the JSON response received from the server: b'Access denied because of exceeding access rate'"
but I dont knw why this error is coming. I was debugging my code from morning. Is it a server error from Angel one? or my code error..
does this lead is also about the same issue I am facing?
