Limit of queries in google API

I'm conducting distance queries using the google API

for r in cursorConsulta:
        googleGeocodeUrl = 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?location='
        punto = str(r[1])+','+str(r[0])
        id = r[2]
        #radioBusqueda = r[3]
        radio = '&radius=4000'
        clave = '&keyword=' + 'anses'
        APIKEY = '&key=' + '****' 
        url = googleGeocodeUrl + punto + radio + clave + APIKEY
        print(url)
        json_response = urllib.request.urlopen(url)
        busqueda = json_response.read().decode('utf-8')
        busquedajson = json.loads(busqueda)
        result =  busquedajson['status']

When the api returns the status

  

OVER_QUERY_LIMIT

Create a new api key to be able to process again

if result=="OVER_QUERY_LIMIT":
 googleGeocodeUrl = 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?location='
        punto = str(r[1])+','+str(r[0])
        id = r[2]
        #radioBusqueda = r[3]
        radio = '&radius=4000'
        clave = '&keyword=' + 'anses'
        APIKEY = '&key=' + '****' 
        url = googleGeocodeUrl + punto + radio + clave + APIKEY
        print(url)
        json_response = urllib.request.urlopen(url)
        busqueda = json_response.read().decode('utf-8')
        busquedajson = json.loads(busqueda)

The question is as follows, enter the first query of the api and reprocess the allowed amount, when it reaches its maximum it enters the if result == "OVER_QUERY_LIMIT": and reprocesses , now when you regenerate the OVER_QUERY_LIMIT message of the second KEY API, how can I do it so that the application will have it if it does not continue running with the query message exceeded.
