NinjaBlocks

Ninja Blocks Inc was an Australian Internet-of-Things startup (founded 2012, backed by 500 Global / 500 Startups) behind the Ninja Block and Ninja Sphere home-automation hubs. It offered a cloud-connected platform with a RESTful API (base https://api.ninja.is/rest/v0/) for reading sensor data and controlling actuators, plus first-party client libraries for Node.js, PHP, Ruby, Lua and Arduino, a `ninja-toolbelt` CLI, and OAuth-based authentication. The company ceased operation and its web and API hosts are no longer online; this profile preserves the surviving first-party open-source client libraries and API tooling published to npm and GitHub. Added to the API Evangelist network from the 500 Global portfolio and enriched from public package registries and the github.com/ninjablocks organization.

NinjaBlocks publishes 1 API on the APIs.io network. Tagged areas include Company, Internet of Things, IoT, Home Automation, and Smart Home.

NinjaBlocks’ developer surface includes CLI and 5 more developer resources.
