Thin cohort — 4 providers, below the 5-provider floor.
This page publishes its roster and deliberately generates no statistics about it. A distribution over
4 providers is not a small
characterisation of rail in United States — it is a wrong one.
Read the number as a statement about what the catalog has profiled, not about the market:
United States holds 297 providers overall and
Rail holds 26.
If a company belongs here and is missing, add it.
Rail in United States — 4 providers on the APIs.io network sit in both cohorts, and between them they publish 31 indexed APIs.
This cell is below the 5-provider floor, so it carries no generated statistics. A distribution over 4 providers is not a small characterisation of rail in United States, it is a wrong one. What follows is the roster and nothing more. The gap is a statement about catalog coverage rather than about the market: United States holds 297 providers in total and Rail holds 26, so the intersection being this small is worth reading as a queue of organisations not yet profiled.
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 rail 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
Rail. 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.
