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 is listed with 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 36 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Education & Research regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
