Cask Data, Inc. was the enterprise big-data startup, backed by Andreessen Horowitz, that built and open-sourced CDAP — the Cask Data Application Platform — a framework for building and running data analytic applications and data pipelines on Hadoop, Spark, Kubernetes, and the cloud. Cask was acquired by Google Cloud; CDAP continues as an Apache-2.0 open source project under the github.com/cdapio organization and powers Google Cloud Data Fusion. CDAP's programmatic surface is its HTTP RESTful "Microservices" API — 21 documented service families (Lifecycle, Artifact, Metadata, Metrics, Logging, Namespace, Pipeline, Preferences, Profile, Provisioners, Replication, Reports, Security, Service, Workflow, Monitor, Dashboard, Configuration, Transaction Service, System Workers) served under a /v3 path prefix from a self-hosted CDAP router, with Bearer access tokens issued by the CDAP authentication server. The company's own cask.co domain and developer portal are gone; the surviving surfaces are cdap.io, the CDAP documentation wiki, the cdapio GitHub organization, and the io.cdap.cdap / co.cask.cdap artifact groups on Maven Central.
Cask publishes 12 APIs on the APIs.io network. Tagged areas include Company, Big Data, Data Analytics, Data Pipeline, and Data Integration.
Cask’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, changelog, and 16 more developer resources.
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.
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/cask: open an issue to ask a question, or submit a pull request to add artifacts.

x-base-url-note: CDAP is self-hosted software; there is no vendor-operated public API host. The documented base URL is http://<host>:<port>
where port defaults to 11015 (router.bind.port), or 10443 when SSL is enabled (router.ssl.server.port). localhost:11015
is the value CDAP's own documentation uses in its curl examples.
