## What this company is

onX is a consumer mapping-software company. The product is the app: land ownership layers,
trail networks, offline maps, waypoints and tracks, delivered through subscription memberships
(onX Hunt Premium and Elite, and the Offroad, Backcountry and Fish equivalents) and through
per-seat onX for Business licenses.

## API surface

**There is none published.** As of 2026-09-18 onX publishes no developer program, no developer
portal, no API documentation, no SDKs, no webhooks and no machine-readable contract. Probed and
confirmed absent on www.onxmaps.com: `/openapi.json`, `/openapi.yaml`, `/swagger.json`,
`/api-docs`, `/docs`, `/redoc`, `/developers`, `/developer`, `/graphql`, `/llms.txt`, `/apis.json`
and the `/.well-known/` discovery set (openid-configuration, oauth-authorization-server,
oauth-protected-resource, api-catalog, ai-plugin.json, agent-card.json, agent.json,
aauth-resource.json) — every one returns HTTP 404. The hostnames api.onxmaps.com,
developer.onxmaps.com, developers.onxmaps.com and docs.onxmaps.com do not resolve.
webmap.onxmaps.com is the login-gated web map application (an SPA that answers 200 with its
shell for any path). The consumer Terms of Use mention "RSS, Data API and/or Widget Services"
only as generic boilerplate; no such service is documented anywhere on the site.

The GitHub organization (https://github.com/onXmaps) holds 30 repositories, 28 of them forks of
open-source geospatial and infrastructure libraries (Cesium, OpenLayers, Mapbox GL JS, GEOS
bindings, Ory Kratos/Hydra, OSM tooling); the two original repositories are internal tooling
(a Cypress IAP plugin and a Paperclip fork). None publishes an API contract.

The only machine-readable endpoint on the domain is incidental to the marketing site's CMS:
the stock WordPress REST root at `https://www.onxmaps.com/wp-json/` — not a product API, not
documented, and not offered to developers. It is not registered as an API in this profile.
