API Endpoint
A URL that returns structured data programmatically instead of a rendered web page.
An API endpoint is a URL designed to be requested by code rather than a browser, returning structured data (usually JSON) instead of HTML. For dataset products, an API endpoint lets a customer pull fresh data on a schedule instead of re-downloading a static export every time.
Example
/dataset-catalog.json on this site is a simple read-only API endpoint -- it returns the current catalog of templates and datasets as JSON.
