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.
