CHOP additionally publishes 320+ public repositories across the `chop-dbhi` (Department of Biomedical and Health Informatics) and `d3b-center` GitHub organizations, plus shared research data platforms including RADIANT, CAVATICA, PedcBioPortal, the Children's Brain Tumor Network, and the Kids First Data Resource Center.
Children’s Hospital of Philadelphia publishes 8 API contracts indexed on the APIs.io network, including Bulk Data API, Patient Access API, Provider Directory API, and 5 more. Tagged areas include Healthcare, Pediatrics, FHIR, SMART on FHIR, and Patient Access.
The Children’s Hospital of Philadelphia catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Children’s Hospital of Philadelphia’s developer surface includes authentication, developer portal, engineering blog, support, and 14 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 does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
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/.
