CDC DIBBs Query Connector API is one of 10 APIs that [Centers for Disease Control and Prevention](https://apis.io/providers/centers-for-disease-control-and-prevention/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include FHIR, HL7v2, Interoperability, Public Health Surveillance, and TEFCA. The published artifact set on APIs.io includes an OpenAPI specification and a changelog.

The DIBBs Query Connector is a FHIR client that lets public health agencies query health care organizations directly or through a TEFCA QHIN. Its published OpenAPI 3.0.3 contract exposes a health check and a query endpoint that accepts either a FHIR R4 patient resource or an HL7 v2 message, with US Core race and ethnicity search parameters drawn from the CDC Race and Ethnicity code system. CDC runs a demo instance tracking the latest release and a dev instance tracking main; the product itself is self-hosted and CC0.
