# Edgebrix > Describe a media transform, serve it as a URL Edgebrix turns a plain-English description of a media transformation into deterministic code, published as an edge-cached CDN URL. Watermarks, OG images, face blur — anything. No code to write, nothing to deploy. ## How It Works 1. Describe the transformation you want (e.g. "stamp our logo bottom-right, auto light/dark"). 2. AI writes deterministic code in a private, isolated sandbox bound to your workspace. Preview it on your own assets, then publish. 3. Call it from a URL: `https://cdn.edgebrix.com//t_[param:value]/`. Deterministic output means every render is edge-cached — repeat requests never touch compute. ## Built-in URL Transforms Resize and crop work directly in the URL, no transform needed: `https://cdn.edgebrix.com//w_800,h_600,c_fill,g_auto/` — `w_`/`h_` for size, `c_fill|c_fit|c_crop` for crop mode, `g_auto` for smart subject-aware cropping. Everything else is a transform you create. ## Getting Started Install via: `npx skills add edgebrix/skills` ## API - API endpoint: https://api.edgebrix.com - CDN endpoint: https://cdn.edgebrix.com - API documentation: https://api.edgebrix.com/swagger ## Links - Website: https://edgebrix.com - Sign up: https://edgebrix.com/sign-up
