All you need is requests. Keep the key in an environment variable.

Poll today's results

import os, time, requests

S = requests.Session()
S.headers["X-API-Key"] = os.environ["KEY"]
URL = "https://api.greyhoundracingapi.com/v1/results/today"
since = time.strftime("%H:%M", time.gmtime())

while True:
    r = S.get(URL, params={"since": since})
    if r.status_code == 429:
        time.sleep(int(r.headers.get("Retry-After", 60))); continue
    since = time.strftime("%H:%M", time.gmtime())
    for race in r.json()["data"]:
        print(race["track_name"], race["no"], race["result"][0]["runner"])
    time.sleep(90)
