API Design & Development
We design and build APIs that developers love to use. From API-first architecture design and OpenAPI specification to implementation, testing, versioning, and documentation, our API engineering team creates robust, well-documented APIs that serve as the backbone of your platform ecosystem. Whether REST, GraphQL, gRPC, or event-driven, we pick the right protocol for each use case.
Why This Matters
APIs are the products of the platform economy. Well-designed APIs reduce integration time by 70%, lower support costs, and become a competitive moat for your platform.
What You Get
Capabilities
API-First Design
Start with the contract — OpenAPI specs reviewed by stakeholders before a single line of code is written, ensuring APIs meet consumer needs.
Developer Portal
Beautiful, interactive API documentation with try-it-out sandbox, code samples in 8+ languages, and SDKs auto-generated from specs.
Event-Driven APIs
WebSocket, SSE, and webhook implementations for real-time data streaming alongside traditional request-response APIs.

Frequently Asked Questions
What is API-first development?
API-first means designing the API contract before implementation. This ensures consistent interfaces, enables parallel development, and makes your platform easily extensible. Masarrati uses OpenAPI/Swagger specifications for all API designs.
How do you secure APIs in production?
Through OAuth 2.0/JWT authentication, rate limiting, input validation, API gateways, DDoS protection, encryption in transit, and regular security audits. Masarrati follows OWASP API Security Top 10 guidelines.
Can you build an API marketplace or developer portal?
Yes. Masarrati builds developer portals with interactive documentation, sandbox environments, API key management, usage analytics, billing integration, and community features for API monetization.
What is the difference between REST, GraphQL, and gRPC?
REST is simple and widely adopted. GraphQL lets clients request exactly what they need. gRPC is fastest for internal microservice communication. Masarrati recommends the right protocol based on your use case and consumer needs.
How do you handle API versioning?
Through URL versioning (v1/v2), header-based versioning, or contract-driven approaches. Masarrati implements backward-compatible changes, deprecation policies, and migration guides to minimize breaking changes.
