FlexGen's own product pages state that HybridOS provides "automated APIs" and, as of the 2026 HybridOS release, "historian data API access" — so an API demonstrably exists — but there is no public developer portal, API reference, or quota/throttling documentation anywhere on flexgen.com, and no api./docs./developer. host resolves in DNS. Any published limits would live inside customer documentation reached through the login-gated portal at portal.flexgen.com. An honest zero: checked, nothing published. api_exists_but_undocumented: true evidence: - url: https://www.flexgen.com/software/hybridos-energy-management-system status: 200 quote: >- HybridOS is a hardware-agnostic EMS platform that enables multi-source and multi-site energy management for peak BESS performance with instantaneous monitoring, web-based controls, and automated APIs. - url: https://portal.flexgen.com/ status: 200 note: Noloco-hosted customer portal; login required, no anonymous documentation.
