Slugify, make a URL slug: turn a title into a clean URL slug

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Turn any text into a URL-friendly slug: accents removed (é→e, ß→ss), lower case, non-alphanumerics replaced by a separator (- by default). Use for file names, URLs and IDs.

Run it free (25 free calls) Buy credits by card (from $1) Example result (JSON)

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/slug?text=Cr%C3%A8me%20Br%C3%BBl%C3%A9e%20%26%20Stra%C3%9Fe!"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/slug?text=Cr%C3%A8me%20Br%C3%BBl%C3%A9e%20%26%20Stra%C3%9Fe!&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "slug": "creme-brulee-strasse"
}
