Fdc3 Finops

FOCUS-aligned FinOps for FDC3: the standard and its reference implementations (TypeScript/ JavaScript npm packages, JSON schemas, OpenAPI App Directory spec) are fully open source with zero API call charges. FinOps for FDC3 adoption therefore tracks implementation and integration costs rather than runtime usage fees. Key cost categories are: (1) engineering effort to integrate the FDC3 API into desktop applications; (2) licensing cost of the Desktop Agent platform chosen (OpenFin, Finsemble, Interop.io — each commercially licensed); (3) optional FINOS membership fees if the organization wants governance participation; (4) infrastructure cost of hosting an App Directory implementation. There is no per-call, per-message, or subscription meter at the FDC3 standard layer.
