Sunlight

Sunlight is an educational-spending platform that lets organizations fund learning for their people. Administrators create groups, invite registered or unregistered members, allocate a per-user education budget ("sunlight"), and let members place orders for courses, books and subscriptions from providers such as Amazon and Platzi, while an activity feed tracks what members join and buy. Its REST API is built on the JSON:API specification (media type application/vnd.api+json) with Bearer-token authentication, and exposes groups, group membership and invitations, per-user credit/budget transactions, orders, and activities. Sunlight was backed by Seedcamp and Speedinvest.

Sunlight publishes 1 API on the APIs.io network. Tagged areas include Company, Education, EdTech, Learning, and Budgeting.

Sunlight’s developer surface includes documentation, API reference, authentication, and 9 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/.

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

  to a decommissioned AWS Elastic Beanstalk environment (sunlight-production.eu-west-1.elasticbeanstalk.com, no A record)
  and the apex sunlight.is TLS endpoint returns a handshake internal-error alert. The Slate developer docs (docs.sunlight.is,
  GitHub Pages) and the Webflow marketing site (www.sunlight.is) remain online. The API surface captured here is faithfully
  harvested from the live public docs; the service itself appears dormant.
