In their own words
API Architect
API Architect is a web product for describing software architecture, business rules, APIs, and AI governance in a shared executable DSL. Its versioned language models systems, containers, and flows, while centralizing DTOs, compliance rules, and operational constraints. From those definitions, it generates APIs aligned with business needs, governance, and standards. Enterprise DSL is presented as a declarative language covering architecture, business, APIs, rules, AI, governance, and compliance. AI systems can load the DSL as an internal model so generated APIs follow business rules and governance boundaries. An example sets a market-specific maximum length for a resource field and defines a GET route returning that resource. Listed use cases include banking and insurance, retail and e-commerce, industry and energy, and SaaS publishers. Free costs nothing for one active project and community support; Starter is €29 a month; Pro is €79 a month.
