OpenFEMA API
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.
