OpenAPI Specification

openapi: 3.2.0
info:
  title: TIGERweb REST Services Catalog API
  description: 'ArcGIS REST endpoints that expose the canonical TIGER/Line geographic

    boundary layers — states, counties, census tracts, block groups, blocks,

    ZIP Code Tabulation Areas (ZCTAs), congressional districts, school

    districts, urban areas, and Public Use Microdata Areas — for current

    vintages and the 2010 and 2020 census decades.


    These are public ArcGIS Server endpoints; no API key is required. Spatial

    queries return GeoJSON, Esri JSON, KML, or PBF based on the `f` parameter.
