# Skuuy APIs (apis.skuuy.com) > Curated Live Public APIs Directory, Health Monitoring Engine & In-Browser Playground Skuuy APIs is an open, modern, and interactive public API directory. It solves the broken links and stale entries of traditional static Markdown directories (such as `public-apis/public-apis`) by actively monitoring API endpoint uptime, response latency, and CORS compatibility. ## Core Features 1. **Live Health Monitoring**: Proactively evaluates HTTP status codes (200 OK, 401/403 Key Required, 404/500 Offline) and response times (ms) across hundreds of public endpoints. 2. **In-Browser API Playground**: Interactive Mini-Postman allowing developers to test GET endpoints with custom parameters directly from their browser, equipped with an optional Edge CORS proxy. 3. **Resurrected Public REST API**: - `GET https://apis.skuuy.com/api/v1/apis` (Filter by `category`, `auth`, `cors`, `status`, `search`) - `GET https://apis.skuuy.com/api/v1/categories` (Summary count per category) - `GET https://apis.skuuy.com/api/v1/random` (Retrieve a verified online random API) - `GET https://apis.skuuy.com/api/v1/probe?url=[endpoint]` (Test latency and status of any endpoint) 4. **Polyglot Code Generator**: 1-click copyable snippets in cURL, JavaScript (Fetch & Axios), Python (Requests), Go, Dart / Flutter, and PHP. 5. **Community Submissions**: External developers can submit new APIs with automated URL reachability validation. ## Supported Categories (50+) - AI & Machine Learning - Animals & Pets - Anime & Manga - Blockchain & Cryptocurrency - Business & Finance - Cloud Storage & DevOps - Development & Programming - Dictionaries & NLP - Entertainment & Games - Environment & Weather - Food & Recipes - Geocoding, IP & Maps - Government & Open Data - Health & Medicine - Music & Audio - News & Feeds - Science & Math - Security & Cryptography - Sports & Fitness - Transportation & Logistics ## Authentication Tiers - `No Auth`: 100% free with no registration or API keys required. - `API Key`: Requires a free registration key sent via query param or header. - `OAuth`: Requires standard OAuth 2.0 client credential exchange. ## Zero Cost & Architecture - Edge Infrastructure: Cloudflare Pages & Pages Functions - Styling: Neo-Brutalist design language (High contrast borders, vibrant accents, hard shadows) - Parent Ecosystem: Skuuy Network (https://skuuy.com)
