Property Data API Review Tool

Property Data API Review Tool (PDART) was created to enable users to view the data and images provided to Fannie Mae’s Property Data Application Programming Interface (API). PDART helps to facilitate quality control of property data provided through the property data collection (PDC) process. Users can assess the accuracy of the property data, identify potential property issues, and confirm that the data provided to Fannie Mae aligns with the user’s internal representation of the data.

Through PDART, users can:

  • View data provided by a property data collector
  • Examine a raw JSON data file delivered through the API
  • View photos and associated metadata delivered as part of a PDC
  • View the subject property location on Google Maps
  • View informational messages about property data
