SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing APIs without robust security, governance, and OpenAPI guidance leads to brittle, vulnerable services. This skill codifies best practices for secure, scalable API design including modern authentication, rate limiting, and proper error handling.

Core Features & Use Cases

  • REST, GraphQL, and gRPC design considerations for building scalable APIs that meet evolving client needs.
  • OpenAPI 3.1, OAuth2/JWT authentication, rate limiting, and pagination strategies to enforce standards and guardrails.
  • Use Case: Architect an enterprise API gateway and secure endpoints across multiple services while maintaining versioning and documentation.

Quick Start

Draft a secure OpenAPI 3.1 spec for a new service, including JWT validation and rate limiting.

FAQPage Schema
How do I design a secure RESTful API with OpenAPI 3.1 specifications?

Design secure RESTful APIs by drafting an OpenAPI 3.1 specification that enforces strict validation, OAuth2/JWT authentication patterns, and robust rate limiting. This approach ensures production-ready endpoints with standardized governance and clear documentation.

What is the best way to implement JWT validation and OAuth2 across multiple services?

Implement JWT validation and OAuth2 across multiple services by integrating an enterprise API gateway. This secures endpoints centrally, enforces authentication guardrails, and maintains consistent versioning across complex service architectures.

How do I handle API errors using RFC 7807 style responses?

Handle API errors using RFC 7807-style responses to provide standardized, machine-readable error details. This format enforces strict validation and returns consistent error structures across all RESTful endpoints.

Does this approach support GraphQL and gRPC design alongside REST?

Yes, this approach supports GraphQL and gRPC design alongside REST. It provides specific considerations for building scalable APIs across these paradigms to meet evolving client needs while maintaining consistent security standards.

When do I need rate limiting and pagination strategies for enterprise APIs?

You need rate limiting and pagination strategies for enterprise APIs when scaling complex services to prevent abuse and manage large datasets. These guardrails enforce standards, protect gateway resources, and ensure stable API performance.
