  HealthData.gov is the U.S. Department of Health and Human Services open data
  platform providing public access to federal health datasets including Medicare
  claims, hospital quality ratings, drug utilization data, public health
  indicators, and data from agencies such as CMS, CDC, FDA, and NIH. The
  platform is powered by the Socrata Open Data API (SODA) and exposes every
  dataset through a consistent REST API using SoQL query language, enabling
  developers to build applications, conduct research, and create data
  visualizations from authoritative government health data.

    description: >
      The Socrata Open Data API (SODA) provides programmatic access to all
      public datasets hosted on HealthData.gov. Each dataset is accessible
      through a unique eight-character identifier inserted into the REST
      endpoint. Queries are expressed using SoQL (Socrata Query Language),
      a SQL-like syntax that supports filtering, sorting, aggregation, and
      pagination. Datasets span Medicare inpatient and outpatient claims,
      hospital compare quality scores, state drug utilization data, community
      health indicators, and thousands of additional HHS datasets. No
      authentication is required for public datasets; an app token raises the
      default request quota significantly.
