SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit REST API contracts to ensure safe, predictable, and backward-compatible changes.

Core Features & Use Cases

  • HTTP Semantics validation: correct usage of GET/POST/PUT/PATCH/DELETE
  • Versioning checks: enforce versioned URLs and deprecation policies
  • Response design: DTOs over entities, consistent response wrappers, and error formats
  • Backward compatibility: detect breaking changes and provide migration notes

Quick Start

Provide your REST controllers or API specifications and I will audit HTTP semantics, versioning, and response consistency.

FAQPage Schema
How do I audit REST API contracts for safety and backward compatibility?

To audit REST API contracts, provide your REST controllers or API specifications. The review enforces correct HTTP semantics, versioning, and response consistency to catch breaking changes and ensure predictable API behavior.

What is the correct way to handle HTTP verbs and error formats in a REST API?

Correct REST API HTTP semantics require proper usage of GET, POST, PUT, PATCH, and DELETE verbs. API response consistency requires a standardized error structure and consistent status codes across all endpoints.

How do I check REST API endpoints for missing versioning and non-standard responses?

You can check REST API endpoints by validating versioned URL paths and deprecation policies. The audit detects missing versioning, incorrect HTTP verbs, inconsistent responses, and non-standard error formats during design reviews or PR checks.

Can I use DTOs instead of raw entities for REST API response design?

Yes, response design validation enforces using DTOs over raw entities. This ensures consistent response wrappers and a standardized error structure across your REST API endpoints for predictable client interactions.

When do I need to validate REST API HTTP semantics before a release?

You need to validate REST API HTTP semantics during API design reviews, PR checks, or pre-release validation. This catches breaking changes, incorrect verbs, and missing versioning before deploying endpoints to production.
