🇺🇸Mining in United States
20 mining providers in United States, publishing 10 APIs.
Mining in United States — 20 providers on the APIs.io network sit in both cohorts, and between them they publish 10 indexed APIs.
6 of the 20 publish at least one machine-readable API; 14 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.
By Kin Score band: 12 minimal, 7 emerging, and 1 thin.
Leading by rating: United States Steel, Alliance Resource Partners, CONSOL Energy, Impossible Metals, Arch Coal, EnergyX, and 14 more.
Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in United States when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.

This page is the intersection of two independently computed cohorts:
United States and
Mining. A provider appears here only when it is
already a member of both. United States membership is matched on tag, stated HQ,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
