Python

Make sure to pip install requests, then use the following sample code to load the surgeries into Python.

import requests

url = "http://yakdb.org/api/knots"

headers = {
    "Accept": "application/json"
}

response = requests.get(url, headers=headers)
data = response.json()
print(len(data)) # print number of records returned

(* 1. Specify the URL *)
url = "http://yakdb.org/api/knots";

(* 2. Directly import and parse as JSON *)
data = Import[url, "RawJSON"];

(* 3. Inspect the result, which should be an Association or list of Associations *)
