api-hardening

What problem does it solve?

API hardening patterns to defend REST APIs from abuse, data leakage, and injection attacks across common runtimes.

Core Features & Use Cases

• Rate limiting, input validation, CORS configuration, API key management, and secure error handling for Express, FastAPI, and serverless architectures.
• Use cases include protecting public APIs, microservices, and admin endpoints in web apps, with defense-in-depth guidance and best practices.
• Practical code patterns, configuration examples, and security checklists to harden services in production.

Quick Start

Implement a basic rate limiter in Express, add input validation in FastAPI with a sample schema, and enable strict CORS and security headers across environments.
