API Architect
What API Architect is
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. It generates APIs aligned with business needs, governance, and standards. The maker describes Enterprise DSL as covering architecture, business, APIs, rules, AI, governance, and compliance. AI systems can load the DSL as an internal model to generate APIs that follow business rules and governance boundaries. An example defines a resource field with a market-specific maximum length and a GET route that returns the resource. Listed use cases include banking and insurance, retail and e-commerce, industry and energy, and SaaS or software publishers. The Free plan costs nothing for one active project, essential features, and community support. Starter costs €29 a month for two active projects, standard API analytics, and support in 48h. Pro costs €79 a month for ten active projects, advanced observability, priority support 7/7, and CRM and payment integrations.
