URL Shorteners — entry 003 of 14
CleanURI
CleanURI is a minimal, free URL shortener with a single documented endpoint: POST /api/v1/shorten takes a (URL-encoded) long URL and returns a short cleanuri.com link as JSON. It needs no account or API key, making it one of the simplest shorteners to call programmatically, though it offers no analytics, custom aliases, or link management beyond creation.
