SpaceAPI

SpaceAPI is an open standard for hackerspaces, makerspaces, fablabs, and similar community spaces to publish real-time information about their spaces in a machine-readable JSON format. It provides a central directory (collector) that aggregates endpoints from participating spaces around the world, enabling applications to discover and display space status, location, contact, and operational information.

SpaceAPI publishes 1 API on the APIs.io network: Directory API. Tagged areas include Co-Working, Event Spaces, Maker Spaces, Hackerspaces, and Community.

The SpaceAPI catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
