SkyFoundry, founded in 2009 and headquartered in Glen Allen, Virginia, develops SkySpark, an analytics and informatics platform that connects, stores, analyzes, and visualizes data from smart devices, automation and control systems, meters, and sensors to "find what matters" in large equipment and facility datasets. SkySpark automatically detects issues, patterns, deviations, faults, and cost-reduction opportunities across intelligent buildings, industrial, agriculture, energy, government, and healthcare facilities, and has been applied to over 15,000 buildings spanning more than a billion square feet. SkySpark is a native Project Haystack server: external applications integrate through the Haystack HTTP REST API (ops such as read, hisRead, hisWrite, pointWrite, watchSub/watchPoll, eval, commit, and nav) with Zinc, JSON, Trio, and CSV data formats, and authenticate using the Haystack SCRAM (SHA-256) handshake with bearer authTokens. The company sells through a network of 140+ OEM, systems-integrator, and value-added-distributor channel partners rather than a self-service public SaaS.
SkyFoundry publishes 1 API on the APIs.io network. Tagged areas include Company, Building Analytics, IoT, Energy Management, and Fault Detection.
SkyFoundry’s developer surface includes documentation, API reference, engineering blog, authentication, and 6 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/skyfoundry: open an issue to ask a question, or submit a pull request to add artifacts.

description: SkySpark is a native Project Haystack server. External applications integrate through the Haystack HTTP REST
API, exposing operations such as about, read, hisRead, hisWrite, pointWrite, watchSub, watchPoll, watchUnsub, nav, eval,
and commit over Zinc, JSON, Trio, and CSV. Endpoints follow the pattern /api/{proj}/{op} on each self-hosted SkySpark
instance; authentication uses the Haystack SCRAM (SHA-256) handshake, after which a bearer authToken is presented via
the Authorization header. There is no single public multi-tenant host — each customer runs its own SkySpark server.
