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.

SpaceAPI’s developer surface includes documentation, GitHub presence, and 4 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/spaceapi: open an issue to ask a question, or submit a pull request to add artifacts.
