ci4-api

What problem does it solve?

This Skill eliminates the risk of building inconsistent, insecure, or hard-to-maintain REST APIs with CodeIgniter 4 by providing standardized, production-ready patterns for response formatting, authentication, validation, and error handling that work seamlessly across web, mobile, and third-party clients.

Core Features & Use Cases

• Standardized API Structure: Enforces consistent JSON response envelopes, proper HTTP status codes, and URL versioning to ensure existing clients never break when updates are deployed.
• Integrated Authentication & Authorization: Implements Bearer token auth, role-based access filters, and full token lifecycle management using CodeIgniter Shield, including login, registration, logout, and scope-based permissions.
• Production-Grade Guardrails: Includes pre-built patterns for rate limiting, CORS configuration, secure webhook handling (Stripe, GitHub), and global JSON error handling for API routes to meet production security and reliability requirements.
• Use Case: For example, use this Skill to build a versioned user management API with public registration/login endpoints, rate-limited authenticated user routes, and a Stripe webhook receiver that follows security best practices.

Quick Start

Ask Claude to implement a versioned CI4 REST API endpoint for user registration with token authentication, input validation, and a standardized JSON success response.
