docker run --rm -p 6379:6379 redis

pip3 install -r requirements.txt

python3 app.py 

curl -v -H "X-API-Key: testkey1" localhost:5000/throttle

Run the above command 7 times. On the 7th run it should return an HTTP status code of 429

The application will return the following headers

 X-Rate-Limit-Hour-Remaining: 5
 X-Rate-Limit-Day-Remaining: 9

That will let the user know how many requests they have remaining before the run over the limit

Data is stored in redis in the format:

"GET" "<X-API-KEY HEADER>:hourly:<BUCKETED_TIMESTAMP>"
"GET" "<X-API-KEY HEADER>:daily:<BUCKETED_TIMESTAMP>"

The hourly key will expire 1 hour and 1 second after the last update in that bucket and the daily will expire in 24 hours and 1 second to keep the keyspace from filling up
