REDCap (Vanderbilt)

REDCap (Research Electronic Data Capture) is secure web software for building and managing online surveys and research databases, created at Vanderbilt and licensed at no cost to non-profit members of the REDCap Consortium. Each institution installs and runs its own server, so there is no central API host: every installation exposes its own token-authenticated /api/ endpoint, and the core API reference sits behind that installation's login.

REDCap (Vanderbilt) is listed with 1 API on the APIs.io network. Tagged areas include Company, Research, Clinical Research, Surveys, and Data Capture.

REDCap (Vanderbilt)’s developer surface includes changelog, authentication, documentation, support, signup flow, pricing, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 the provider profile at artifacts.apis.io/projectredcap-org/apis.yml: open an issue on github.com/api-evangelist/projectredcap-org to ask a question or point us at an artifact you publish.
