      The OpenFEMA API is FEMA's public RESTful service that exposes more
      than 70 datasets including disaster declarations, public assistance
      funded projects, individual assistance grants, hazard mitigation, and
      housing assistance program data. The API is free, requires no API key,
      and supports OData-style query string parameters for filtering, sorting,
      pagination, and field selection. Default page size is 1,000 records up
      to a maximum of 10,000.
