**APIs profiled:** 9

Union.ai is the commercial AI/ML orchestration platform built on the open-source Flyte project. It exposes the Flyte/Union control plane (the FlyteAdmin service) for registering and running strongly-typed workflows, tasks, and launch plans, plus Union Serverless, Actors, and Artifacts. The control plane is primarily a gRPC API (FlyteIDL AdminService) with an auto-generated HTTP/JSON gateway exposed under /api/v1/, driven by the union / pyflyte CLI and Flytekit / Union SDKs.
