ARC Geospatial API

Anonymous query access to the 108 public hosted feature services in the Appalachian Regional Commission's own ArcGIS Online organization (org id nkunl3y8FDxPkXDl, portal arcgov.maps.arcgis.com). This is where ARC's numbers live in machine-readable form: the ARC region boundary, the 423 Appalachian counties keyed on FIPS, the 74 Local Development Districts, congressional districts, rural-urban county types, and the annual county economic-status designations from FY2014 through FY2027 alongside ACS poverty, median household income, SNAP, broadband, education-attainment and population-change series. Returns Esri feature JSON, RFC 7946 GeoJSON or PBF.

Where this information came from

This is an independent, third-party profile of ARC Geospatial API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
