# API Endpoint Builder Build complete, production-ready REST API endpoints with proper validation, error handling, authentication, and documentation. ## When to Use This Skill - User asks to "create an API endpoint" or "build a REST API" - Building new backend features - Adding endpoints to existing APIs - User mentions "API", "endpoint", "route", or "REST" - Creating CRUD operations ## What You'll Build For each endpoint, you create: - Route handler with proper HTTP method - Input validation (request body, params, query) - Authentication/authorization checks - Business logic - Error handling - Response formatting - API documentation - Tests (if requested) ## Endpoint Structure ### 1. Route Definition ```javascript // Express example router.post('/api/users', authenticate, validateUser, createUser); // Fastify example fastify.post('/api/users', { preHandler: [authenticate], schema: userSchema }, createUser); ``` ### 2. Input Validation Always validate before processing: ```javascript const validateUser = (req, res, next) => { const { email, name, password } = req.body; if (!email || !email.includes('@')) { return res.status(400).json({ error: 'Valid email required' }); } if (!name

Run `npx skills add sickn33/agentic-awesome-skills --skill api-endpoint-builder --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
