  title: CDC Socrata Open Data API (data.cdc.gov) SODA v2.1 API
  description: 'REST/JSON access to hundreds of CDC datasets published on data.cdc.gov via

    the Socrata SODA (Socrata Open Data API) platform. Each dataset is

    addressed by an eight-character dataset identifier and supports filtering,

    aggregation, and pagination through SoQL query parameters. Anonymous use

    is allowed at throttled rates; an application token (passed via the

    X-App-Token header or $$app_token query parameter) raises limits. SODA v3

    additionally supports authenticated user requests for non-public datasets.

    Generated as a best-effort spec from public Socrata documentation; verify

    against https://dev.socrata.com/docs/endpoints.html before production use.
