🇺🇸Human Resources & Payroll in United States
88 human resources & payroll providers in United States, publishing 66 APIs.
Human Resources & Payroll in United States — 88 providers on the APIs.io network sit in both cohorts, and between them they publish 66 indexed APIs.
30 of the 88 publish at least one machine-readable API; 58 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: 41 emerging, 27 minimal, 10 thin, 6 developing, and 3 strong.
Leading by rating: RocketReach, Assembled, Yoodli, University of Wisconsin-Madison, Justworks, Phenom, and 82 more.
Country membership reads a tag or a stated headquarters. A provider lands in United States when one of its own top-level tags names the country, or when its own description states a headquarters that names the country or one of its cities (roadmap#542, #719). A description that calls a company by its nationality, or names a city in a phrase that is not a headquarters statement, is not counted, so this cell is a floor, not a census.

Human Resources & Payroll elsewhere
This page is the intersection of two independently computed cohorts:
United States and
Human Resources & Payroll. 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.
