# HostDir Knowledge Bundle

HostDir (https://hostdir.net) is an independent directory of the web-hosting industry. This bundle is published in the [Open Knowledge Format](https://github.com/GoogleCloudPlatform/knowledge-catalog/tree/main/okf) (OKF v0.1) so AI agents and analytics tools can consume our data with full semantics — field meanings, relationships, and where to access each dataset. Everything is openly available; no key or account required.
