Drillster

Drillster is a Utrecht-based adaptive learning platform for corporate and vocational training, built on repetition-based drills that schedule practice at the moment a learner is about to forget.

For developers, Drillster publishes a documented REST API (version 2.1.1, JSON over HTTPS, OAuth 2.0 with a JWT-bearer service-account grant) covering user provisioning, group and membership management, catalogs, drills, tests, objectives and results reporting; an outbound event notification service with seven webhook event types and a seven-day retry contract; an embeddable widget family with a JavaScript loader; and standards-based LMS integration through LTI 1.0/1.3, SCORM 1.2 and OpenID Connect single sign-on.

Drillster publishes 1 API on the APIs.io network. Tagged areas include Assessments, Education, Learning, Quizzes, and Training.

The Drillster catalog on APIs.io includes 1 event-driven AsyncAPI specification.

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/.

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/drillster: open an issue to ask a question, or submit a pull request to add artifacts.
