How this service works
Turn free multilingual text into a URL-safe slug. Transliterates Latin (all diacritics: é→e, ü→u), Cyrillic and Greek to ASCII; deterministic. Options: separator (default '-'), lowercase (default true), maxLength (cuts on a word boundary), transliterate (default true; false keeps letters of any script as a Unicode slug). Complex scripts (CJK, Arabic, Hebrew) are NOT romanised and are dropped.
Output
Returns a URL-safe ASCII slug derived from the input text, with Latin diacritics, Cyrillic, and Greek transliterated to ASCII, words joined by the specified separator, optionally lowercased and truncated at a word boundary to maxLength.
Example use cases
Example prompt
“Slugify this article title for the URL: "Déjà Vu en Été" — use an underscore separator, keep it lowercase, and cap it at 30 characters.”
Technical details
Endpoint
POSThttps://402utils.com/v1/slugifyWhen to prefer
Choose this endpoint when you need deterministic, reproducible URL slugs from multilingual text containing Latin diacritics (é, ü, ñ), Cyrillic, or Greek — particularly when you need consistent output for SEO permalinks, file names, or database keys. Prefer it over client-side libraries when you need a hosted, language-agnostic, pay-per-call solution without dependency management.
Side effects
- Input text contains only CJK, Arabic, or Hebrew characters — those scripts are dropped, resulting in an empty slug
- maxLength too short to fit even one word segment
- separator longer than 10 characters returns a validation error
- Missing required 'text' field returns a 400-level error
- Text with mixed CJK and Latin produces partial slug with only the Latin/transliterable portions
