ARC Taxonomy API

Anonymous read access to the 34 controlled vocabularies ARC classifies its content with — states_counties (446 terms), investment_priority_topic (22), tax_year (70), global_type (31), the research, fact-sheet, event, staff and grant-resource vocabularies — plus the /wp/v2/types, /wp/v2/taxonomies and /wp/v2/statuses registries that describe the content model itself. ARC's content has no foreign keys; these terms are the join.

ARC Taxonomy API is one of 7 APIs that Appalachian Regional Commission publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include Taxonomy, Vocabularies, Metadata, Open Data, and Regional Data. The published artifact set on APIs.io includes an OpenAPI specification and an API reference.

This API exposes 74 operations across 74 paths, and defines 1 schema. It is described by OpenAPI 3.1.0, at version wp/v2.

Requests are made against a single base URL, https://www.arc.gov/wp-json.

Where this information came from

This is an independent, third-party profile of ARC Taxonomy 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.
