Cosmoplat

COSMOPlat (卡奥斯 COSMOPlat) is the industrial internet platform incubated by Haier Group and operated by COSMOPlat Digital Technology (Qingdao) Co., Ltd. Launched in 2017, it was China's first self-developed industrial internet platform built around mass customization, digitally integrating user interaction, R&D, procurement, production and service across a factory and its supply chain. Its product line spans smart-factory and MES systems, industrial IoT device connectivity, chemical-park management, smart energy control, equipment health management and a D3OS digital-twin offering, and it has been applied across roughly twenty industries and more than twenty countries. The developer-facing surface is the 物联开发平台 (IoT development platform), which publishes a public HTML API reference covering product, device, alarm, rule-chain, thing-model, telemetry and device-RPC operations, alongside an MQTT telemetry publish/subscribe surface. COSMOPlat also runs an open-source developer community at openlab.cosmoplat.com and a GitHub organization at cosmoplat-dev.

Cosmoplat publishes 10 APIs on the APIs.io network, including IoT Telemetry (MQTT), Alarm Records API, Alarm Rules API, and 7 more. Tagged areas include Company, Industrial Internet, Industrial IoT, Internet of Things, and Manufacturing.

The Cosmoplat catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

Cosmoplat’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, product news, authentication, and 21 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
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/cosmoplat: open an issue to ask a question, or submit a pull request to add artifacts.
