SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill secures API routes by implementing authentication, authorization, and input validation to prevent unauthorized access and data leakage.

Core Features & Use Cases

  • Authentication: Verify identities using tokens (JWT, sessions, API keys) and manage expirations.
  • Authorization: Enforce RBAC and resource-level permissions to restrict access.
  • Input Validation: Sanitize inputs and validate types to prevent injections.
  • Rate Limiting & CORS: Implement per-user/IP limits and proper cross-origin handling.

Quick Start

Use the api-protect skill to scaffold a secure API route with authentication, RBAC checks, and input validation.

FAQPage Schema
How do I secure API endpoints with RBAC and JWT in Next.js?

You can secure API endpoints with RBAC and JWT in Next.js by enforcing authentication, role-based authorization, and token validation. This approach protects CRUD routes and admin actions from unauthorized access and data leakage.

What is the best way to implement input validation and sanitization for API routes?

The best way to implement input validation for API routes is by using Zod to sanitize inputs and validate types. This prevents injection attacks by ensuring only properly formatted data reaches your backend logic.

Can I use this API security approach with Supabase and custom backends?

Yes, this API security approach works with Supabase, Next.js, or custom backends. It applies token validation, resource ownership checks, rate limiting, and optional CORS handling to protect web application endpoints.

How do I add rate limiting and CORS handling to protected API endpoints?

To add rate limiting and CORS handling to protected API endpoints, you enforce per-user and per-IP limits alongside proper cross-origin resource sharing configuration. This prevents abuse and secures your API routes.

Does API authentication and authorization support resource ownership checks?

Yes, API authentication and authorization support resource ownership checks. By enforcing RBAC and resource-level permissions, the system restricts access so users can only interact with data they explicitly own.
