Query Builder
National Statistical provides an interactive web application to assist with the creation and testing of valid URIs.
Access the Query Builder(s) that you are authorized to use under NatStat API on this page's navigation menu, or from the Analysis tab in any of the 30 league hubs you have access to. Look for Query Builder.
You can easily and quickly regenerate your API key with the link at the top of the screen. The number in the upper right corner is the number of API calls you have remaining for the current hour (:00 to :59) or day (API+ customers), and the number of minutes before your rate limit resets.
Create a URI with the text fields and pulldown menus, based on the displayed query parameters. Test the query by clicking Execute API Call. Copy the URI or the query output to your clipboard with one click. There is also an open-text field for team and player ID lookups.
