OpenAPI Initiative, hosted by The Linux Foundation, maintains the OpenAPI Specification, the world's most widely used standard for describing HTTP APIs. It governs the development of OpenAPI and related specs, supports governance bodies and member participation, and promotes interoperability across tooling and teams. The initiative publishes the latest specifications, resources, and events (such as the OpenAPI Summit) and fosters adoption through registries, overlays, and implementations in the API ecosystem.
