There is no keyless playground. ## Compliance and transparency - [ONC certification and cost considerations](https://carefluence.com/onc-certification/) - [CHPL listing 10922](https://chpl.healthit.gov/#/listing/10922) - [Real World Testing plan 2025](https://carefluence.com/real-world-testing-plan-2025/) (also [2024](https://carefluence.com/real-world-testing-plan-2024/), [2023](https://carefluence.com/real-world-testing-plan-2023/), [2022](https://carefluence.com/real-world-testing-plan/)) - [OpenAPI terms and conditions](https://carefluence.com/openapi-terms-conditions/) ## Products - [FHIR-based OpenAPI Platform](https://carefluence.com/products/fhir-based-openapi-platform/) - [FHIRops (asynchronous interoperability)](https://carefluence.com/products/fhirops/) - [FHIRone Platform](https://carefluence.com/products/fhirone-platform/) - [Data Translator for data normalization](https://carefluence.com/products/data-translator-for-data-normalization/) - [OAuth 2.0 and OpenID Server](https://carefluence.com/products/oauth-2-0-and-openid-server/) - [Infrastructure for SMART-on-FHIR applications](https://carefluence.com/products/infrastructure-for-smart-on-fhir-applications/) - [Adapters for non-FHIR server connectivity](https://carefluence.com/products/adapters-for-non-fhir-server-connectivity/) - [Built-in integration engine](https://carefluence.com/products/built-in-integration-engine/) - [MCP Server (announced)](https://carefluence.com/mcp-server/) ## Client libraries Three first-party .NET packages on NuGet, all stale โ€” newest release 2019-03-04, more than three years before the R4 API they wrap was certified: - [Carefluence 1.7.0](https://www.nuget.org/packages/Carefluence) (2019-02-21) - [Carefluence.CDSHooks 1.0.0.7](https://www.nuget.org/packages/Carefluence.CDSHooks) (2019-03-04) - [Carefluence.Adapter.13.0 13.0.0](https://www.nuget.org/packages/Carefluence.Adapter.13.0) (2017-06-21) There is no npm, PyPI, Maven, Go or Rust client and no GitHub organization. ## What is NOT published An agent should not go looking for these โ€” they were probed on 2026-09-02 and do not exist: - No OpenAPI or Swagger document. Despite the product being named "OpenAPI", "OpenAPI" here means "open API"; the machine-readable contract is the FHIR CapabilityStatement. - No AsyncAPI document, despite FHIRops being described as AsyncAPI-based. - No reachable MCP server: the product page publishes no endpoint, no install command and no package. - No A2A agent card at /.well-known/agent-card.json or /.well-known/agent.json on any host. - No security.txt, no /.well-known/api-catalog, no trust center, no status page, no changelog, no published rate limits, no priced plans. - `docs.carefluence.com` is a dangling CNAME to SwaggerHub's ingress and serves nothing (Cloudflare error 1001 / TLS handshake failure). ## More - [Company site](https://carefluence.com/) - [News and blog](https://carefluence.com/news-blogs/) ([RSS](https://carefluence.com/feed/)) - [Our Excellence (company milestones)](https://carefluence.com/our-excellence/) - [Glossary of terms](https://carefluence.com/glossary-of-terms/) - [Contact](https://carefluence.com/reach-us/) - [LinkedIn](https://www.linkedin.com/company/carefluence/)
