Data Exporter

Export impact data via JSON or CSV

Say you want to find the busiest days in Austin, Texas in betweeen May and October 2019. Select the Aggregate Event Impact endpoint and select parameters. For this query, we simply use start and end date, timezone, impact rank and place.exact. The output would be a CSV or JSON file that provides data around how many people will be in the city of Austin for events throughout your selected date range.

All API features
PredictHQ's Demand Intelligence API was built with advanced feature engineering to expedite your forecasting and unlock revenue and efficiency opportunities for your business.
  • Radial search
    Need to know events happening within a mile of you? Use the "within" parameter to search for events happening within a certain distance of a specific point, such as a hotel or retail store.
    Radial search
  • NLP Labels
    PredictHQ uses natural language processing (NLP) and machine learning to classify events into niche subtypes to better identify their exact predicted impact.
    NLP Labels
  • PHQ End Times
    Some event data sources provide start times but none provide the end times for every event. This is critical for transport, delivery and ride-sharing companies that want to ensure drivers are at a location when an event ends.
    PHQ End Times
  • Geocoded Events
    Many of the events we aggregate are incorrectly geocoded or missing geocoding all together. Our systems ensure every event available through PredictHQ is correctly geocoded.
    Geocoded Events
  • Umbrella Events
    There are often many individual events within a single larger event. The single larger event is called an umbrella event. Easily search and filter by overarching events e.g. a festival as the umbrella event and the individual performances under it. Some businesses are only interested in the umbrella event whereas others are more interested in the individual events under it. Sometimes perhaps both.
    Umbrella Events
  • PHQ Attendance
    A numerical value that reflects the predicted attendance for supported attendance-based categories. The following categories are supported: concerts, performing arts, sports, expos, conferences, community and festivals.
    PHQ Attendance
  • Location search parameters
    Search, filter and analyze events in specific locations using latitude and longitude geocenter and radius, or by airport codes such as IATA, ICAO, UN/LOCODE. You can also search by country, continent, state, region, province, county or city using our Places API.
    Location search parameters
  • Recurring Events
    Many events recur but 85% of recurring events change location or date each time. By using recurring events, you'll have the ability to move beyond “we had a spike here last year” to pinpointing exactly why you experienced that spike and ensuring you can meet it again.
    Recurring Events
  • Geographical place scope
    Hierarchies are accounted for within our ranks with geographical scope e.g. events that occur at a country level vs. events that happen at a region or city level.
