Learnosity

Learnosity is an Irish-founded assessment infrastructure company whose APIs are embedded into other companies' learning products rather than sold as a finished platform. The surface is split in two: a family of versioned client-side JavaScript APIs - Items, Assess, Questions, Question Editor, Author, Author Aide, Annotations, Events, Reports, Grading, Rubric Editor and Feedback Aide - that render assessment, authoring, grading and reporting experiences inside a host application, and a server-side Data API for Item bank content, learner sessions, responses, scoring, jobs, reports and consumer administration. Learnosity is explicitly not a REST API: every Data API call is an HTTP POST whose operation is chosen by an `action` parameter, and every request across every API carries an HMAC-SHA256 signed `security` object generated server-side by one of six official SDKs. Versions ship on a dated Long Term Support train (vYYYY.X.LTS) pinned in the URL, with regional endpoints in Virginia, Dublin, Sydney, California and Oregon.

Learnosity publishes 12 APIs on the APIs.io network. Tagged areas include Education, Assessment, EdTech, Learning, and Analytics.

Learnosity’s developer surface includes developer portal, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 34 more developer resources.
