Human Services Data API (HSDA)
The Human Services Data API (HSDA) is the interface standard that puts the Human Services Data Specification (HSDS) to work over HTTP. Defined as a set of API paths (with OpenAPI definitions) for reading and writing organizations, services, locations, taxonomies, and their sub-resources, HSDA lets applications query and maintain community resource directories through a consistent, machine-readable contract.
