Crystal

Crystal (Crystal Semiconductor) was a hardtech company that designed audio and mixed-signal semiconductor chips. Kleiner Perkins partnered with the company in 1986 at the early stage, and Crystal was subsequently acquired by Cirrus Logic. The company was surfaced from the Kleiner Perkins portfolio and added to the API Evangelist network as a lead. It operated as a fabless chip designer rather than a software or platform business, and no longer exists as an independent entity: it publishes no website, no developer portal, and no public API surface of any kind. This profile is retained as a historical portfolio record and is not an API provider.

Crystal is profiled on the APIs.io network. Tagged areas include Company, Hardtech, Semiconductors, Hardware, and Audio.

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/crystal: open an issue to ask a question, or submit a pull request to add artifacts.
