  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.
