Get Suggested Radius

Take the guesswork out of working out a suitable radius around your business when searching for events.

The Suggested Radius API returns a radius that can be used to find attended events around a given location. When looking for events around a business location (such as a store, a hotel, or another business location) a key question is how far should you look for events. For example, should you look at events in a 0.5-mile radius, a 2-mile radius, or a 10-mile radius from your location? The Suggested Radius API answers this question by returning a radius based on a number of factors that can be used to retrieve events around a location. This radius returned by the API is commonly used as follows:

• When querying the Events API using the within parameter.

• When calling the Features API with a latitude, longitude, and radius to get aggregated features back for a location.

• For retrieving events in a data lake by setting the radius around a store or location to the suggested radius.

• In-demand forecasting when building event-based features for a location, use this radius when calculating features for a location.

• For use with our Beam product when performing a correlation analysis

The Suggested Radius API is powered by a machine learning model that looks at factors like population density, the events around a location, the customer’s industry, and many other factors to determine the ideal radius.

We'd suggest caching the Suggested Radius API response where possible. The response will only change infrequently and it would be sufficient to refresh the cache once per month.

Request

HTTP Request

GET https://api.predicthq.com/v1/suggested-radius/

Query Parameters

Field	Description
location.origin geopoint	A comma-separated string consisting of the latitude and longitude of the location to find the optimal radius for. For example your store or hotel location. The format is <latitude>,<longitude> E.g. ?location.origin=37.747767,-122.455320
radius_unit string	Unit in which the suggested radius will be returned. The default unit is m Possible values: m - meters (default) km - kilometers ft - feet mi - miles E.g. ?radius_unit=km
industry string	The industry of interest that the radius will be calculated for. For different industries, the radii will be different based on the different types of events that would impact the location. For example, if you were getting the suggested radius around a hotel you’d specify accommodation as the industry. The default industry is other Possible values: parking restaurants retail accommodation other(default) E.g. ?industry=accommodation

Response

Response Fields

Field	Description
radius float	The suggested radius for a given location rounded to 2 decimal places.
radius_unit string	The unit of the radius returned. This will be the unit specified in the industry parameter in the call made.
location object	A json object representing the geo location of the event. E.g. { "lat": 37.747767, "lon": -122.455320 }
