  1. 1. InnovaChallenge Data API
  2. 2. Innova Challenge API What is it? The InnovaChallenge Data API offers aggregated statistics of spending by geographical area, temporal period and commercial category, accesible through a REST services API.
  3. 3. Innova Challenge API Which are the data sources? (1/2) The statistics exposed through the InnovaChallenge Data API come from a dataset that contains transactions performed with BBVA cards, properly anonymized and aggregated. Scope: •  Madrid and Barcelona provinces •  Timespan: 2012-11 – 2013-04 •  Classified into commercial sectors of activity Some metrics about the data: •  More than 30 million transactions •  More than 2 million cards •  More than 200,000 stores Overall, BBVA has a 15-20% market share in card payments.
  4. 4. Innova Challenge API Which are the data sources? (2/2) Each transaction has several parameters associated that describe the context of the purchase made: •  •  •  •  •  •  Transaction amount Time & date of the purchase (timestamp) Store location (lat/lon coordinates). Commercial category of the store. Demographic segment of the cardholder. Zip code of residence of the cardholder. This data, processed and aggregated, provide the basis for the API services. These allow to gain relevant insights on the commercial activity in a given geographical area, for a specific activity sector, for a specific timeframe and a customer segment.
  5. 5. Innova Challenge API Statistics: spatial detail The API offers data about geographical areas in two different partitions for the Madrid and Barcelona provinces: - Zip codes - Zoom 2 cells (450x550m) •  These cells have a size determined by half of a hundredth of a decimal lat/ lon coordinate. The cells are centered in coordinates with the third decimal place set to 0 or 5. Some examples: (40.415, -3.705), (40.420, -3.705), (40.415, -3.710), (40.420, -3.710) •  To ask for a cell it’s enough to call the services with a point contained in such cell.
  6. 6. Innova Challenge API Statistics: temporal detail - Timeframe: 2012-11 – 2013-04 - Data is aggregated by weeks and months. •  Week number 1 in a given year is considered to be the week that has more than 4 days within the given year. •  To ask for statistics of a given week or month, just specify a day that belongs to the period of interest in the API call. 40 41 42 43 44
