🇺🇸Energy in United States

29 energy providers in United States, publishing 50 APIs.

29 providers 50 published APIs 315 indexed documents

Energy in United States — 29 providers on the APIs.io network sit in both cohorts, and between them they publish 50 indexed APIs.

22 of the 29 publish at least one machine-readable API; 7 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: 11 developing, 6 emerging, 4 thin, 3 strong, 3 minimal, and 1 exemplar.

Leading by rating: Enphase Energy, OpenADR Alliance, Green Button Alliance, ERCOT, Pacific Gas and Electric, Voltus, and 23 more.

Country membership is exact-tag only. A provider lands in United States when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a energy company headquartered in United States that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

This page is the intersection of two independently computed cohorts: United States and Energy. A provider appears here only when it is already a member of both. United States membership is matched on tag, 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.
