What is API Design?
API Design is the process of creating a blueprint for your APIs that ensures they are functional, maintainable, and scalable.
API Design is the process of creating a blueprint for your APIs that ensures they are functional, maintainable, and scalable. With EC-API-Design, you can model both functional relational data models and hierarchical message structures, which form the foundation for consistent and reusable API contracts.
Who is API Design For?
API Design is essential for any organization that wants to create robust, scalable, and maintainable APIs.
Our API Design services are built for enterprises that need robust, future-proof integration between systems. Whether you’re a CTO, Enterprise Architect, Data Architect, or Integration Lead, our solutions help bridge the gap between business and IT—enabling you to define, manage, and scale high-quality APIs and data contracts across complex environments. EC-API-Design supports importing existing API contracts and enterprise architecture outputs for analysis, ensuring alignment with your current landscape. From large corporations managing multi-cloud infrastructures to SaaS vendors and regulated industries, if consistency, speed, and governance are critical, our API design approach is for you.
Our API Design Services
Discover how our services can help you create better APIs.
Key Features
Our platform offers powerful features to help you design better APIs.
Model-Driven Design
Build APIs from business requirements, not code, ensuring every contract reflects real business logic through functional relational data models and hierarchical message structures.
Multi-Standard Support
Output contracts in OpenAPI, RAML, WSDL, AsyncAPI, and more, including API scaffolding in Java/C# and comprehensive documentation. No lock-in.
Consistency Engine
Guarantee 100% alignment between business, technical, and integration layers.
Visual & Code Editors
Work visually or directly in YAML—whatever fits your workflow.
AI-Assisted Modeling
Accelerate design with GenAI and automate repetitive modeling tasks.
On-Prem & SaaS
Secure, enterprise-ready deployments on your terms.
How It Works
Capture Requirements
Start with business requirements and functional data models.
Model Your Contracts
Use our platform to create functional API contracts, mapping to message and transaction models.
Automate Output
