Use the World Tides API to retrieve tidal information for anywhere in the world. World Tides API accepts calls via GET or POST, returns data in JSON, and supports both HTTP/HTTPS. Developers will receive an API Key for authentication after registering with World Tides. The API will return information on: the coordinates of the closest point where tidal information is available, the height of tides at a given time, or tidal data so that users can calculate tide heights at a given time. See World Tides API documentation for more information and code examples.
