API Forge

All-in-one developer toolkit API. 156 endpoints for text processing, readability scoring, sentiment analysis, math/statistics, barcode generation, MIME type detection, URL parsing, encoding, hashing, validation, QR codes, language detection, cron parsing, fake data, and more.

Zero dependencies. Runs on Cloudflare Workers (free tier) and Node.js.
