The Appalachian Regional Commission (ARC) is a federal-state partnership that invests in Appalachia's economic future by funding projects that promote economic development, infrastructure improvement, workforce training, and community development across 423 counties in 13 states. ARC runs no developer program and publishes no API documentation, but it operates two live, anonymous, machine-readable surfaces: the WordPress REST API behind www.arc.gov, which serves its research reports, maps, resources, investment priorities, local development districts, events and staff as JSON; and 108 public hosted feature services in its own ArcGIS Online organization, which carry the region's boundaries and the annual county economic-status, poverty, income, SNAP, broadband, education and population series. Neither needs a key.
Appalachian Regional Commission publishes 6 APIs on the APIs.io network, including ARC Research and Data API, ARC Geospatial API, ARC Programs API, and 3 more. Tagged areas include Appalachia, Economic Development, Federal-Government, Geospatial, and Government.
Appalachian Regional Commission’s developer surface includes documentation, API reference, developer portal, support, engineering blog, YouTube channel, authentication, and 21 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Government & Public Sector regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
