SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

REST API design often suffers from inconsistent resource naming, unclear error handling, and fragmented versioning strategies across services. This Skill provides standardized patterns and pragmatic guidelines to unify naming, HTTP semantics, pagination, filtering, and rate limiting for production APIs.

Core Features & Use Cases

  • Clear Resource Naming and URL Structure: guidance on nouns, plurals, kebab-case endpoints, and logical sub-resources (e.g., /api/v1/users, /api/v1/users/:id/orders).
  • Consistent HTTP Semantics: recommended methods, idempotency guidance, and standard status codes for common outcomes.
  • Versioning Strategy and Rate Limiting: strategies for version lifecycles, deprecation, and rate limiting patterns to protect APIs.
  • Error Handling & Response Formats: guidance on structured error payloads, field-level validation, and predictable error codes.
  • Use Case: audit and evolve API contracts to align with a single, coherent design standard across services.

Quick Start

Review the current API surface and align endpoints to the recommended naming, methods, and status codes.

FAQPage Schema
How do I standardize REST API resource naming and URL structure?

To standardize REST API resource naming, use plural nouns, kebab-case endpoints, and logical sub-resources like /api/v1/users/:id/orders to ensure consistent URL structures across services.

What is the best way to structure REST API error handling and response formats?

The best way to structure REST API error handling is using structured error payloads with predictable error codes and field-level validation to provide clear, consistent failure responses.

How do I implement REST API versioning and deprecation strategies?

Implement REST API versioning by defining version lifecycles and deprecation strategies within your contracts, ensuring smooth transitions and consistent HTTP semantics across evolving endpoints.

Can I use this to audit existing API contracts for consistency?

Yes, you can audit existing API contracts by reviewing current endpoints and aligning them against standardized patterns for naming, HTTP methods, status codes, and pagination.

What HTTP methods and status codes should I use for REST API pagination and rate limiting?

Use standard HTTP methods and status codes for REST API pagination and rate limiting, applying idempotency guidance and rate limiting patterns to protect API endpoints from excessive requests.
