Kno2 provides Interoperability as a Service for healthcare - a single Communication API to SEND, RECEIVE, and FIND patient information across the healthcare ecosystem. One connection reaches Direct Secure Messaging, clinical document exchange, HL7 FHIR resources, HL7 V2.x, cloud fax, and national record location and retrieval through Kno2's private network, Carequality, eHealth Exchange, and TEFCA (Kno2 is a federally designated QHIN). API access is partner/enterprise gated - integrators are provisioned a per-subscription tenant host with OAuth2 client-credentials keys and an IP allowlist; a staging sandbox is available through the Kno2 Developer Program.
