Retrieve Records

Access this data through the CKAN Datastore API with resource_id="b076ced6-ef48-45b8-8db2-dd7d27c11fe2"

The CKAN API uses a JSON-RPC style, where you post a JSON object and receive another JSON object in response.

Retrieving records requires an API key. Your API key is shown on your profile page.

Do not include your API key in any code shared with other people. Use a configuration file or environment variable to let each user input their own key when they use your tool. Your API key is equivalent to your password and may be used to perform any action your user can on this site. All actions made with your API key will be logged as actions you performed. Example:

Answers to shopping list, generation, iteration, decoration exercises posted
def shopping_list():
Exercise: shopping list
