Ceros

Ceros is an experiential content platform used by marketing, design and agency teams to build interactive, no-code web content — microsites, landing pages, interactive reports, infographics, pitch decks and embeddable experiences — in a browser design studio and publish them to a CDN. Its developer surface is three separate things. A small read-only REST Public API at rest.ceros.com walks accounts, folders, experiences and embed codes behind a bearer API key, versioned by dated snapshots selected with the x-ceros-api-version header. A browser-side Flex Experience SDK, delivered as an ES module from the Ceros CDN, scripts a published experience at runtime — setting text, controlling media and states, toggling visibility and navigating pages. And a public oEmbed 1.0 endpoint on view.ceros.com, together with first-party connectors for Adobe Experience Manager, Contentful, Optimizely and WordPress, places an experience inside another platform. Ceros also operates MarkUp, its visual commenting and collaboration product.

Ceros publishes 6 APIs on the APIs.io network, including Accounts API, Embed Codes API, Experience API, and 3 more. Tagged areas include Content Management, Interactive Content, Digital Experience, Embed, and oEmbed.

Ceros’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 26 more developer resources.

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