Ursa Computing was a startup founded in 2020 by Wes McKinney (creator of pandas, co-creator of Apache Arrow) to accelerate Apache Arrow and open source data science tooling, backed by GV. In late 2021 Ursa Computing and Ursa Labs joined forces with other teams to form Voltron Data, and the company no longer operates independently: ursacomputing.com no longer resolves, and its remaining public footprint is the ursacomputing GitHub organization, whose crossbow repository still runs extra CI for Apache Arrow. No public API surface was ever published under the Ursa Computing name.
Ursa Computing is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Data, Apache Arrow, and Open Source.
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 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/.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
