The LessCMS headless API — content for your own front end

# fetch collection entries curl -H "X-API-Key: $KEY" \ https://api.lesscms.io/v1/{project}/collections/projects # response { "data": [ { "slug": "brand-shoot-law-firm", "name": "Brand shoot — law firm", "client": "Wroblewski Law", "shoot-date": "2026-05-12", "gallery": [ "…/01.jpg", "…/02.jpg", "…/03.jpg" ] }, … ], "meta": { "total": 7, "lang": "en" } }

Read-only, secured with a key

The API exposes published content only and requires a project key. There is no risk of anyone changing something through it.

Cache tags for selective purging

Responses carry headers that let you purge exactly what changed from the CDN — instead of invalidating the whole site.

Everything available the same way

Pages, collections, menus, blocks, elements, redirects, sitemap and robots — one address pattern for every resource.

The panel comes free

You do not have to build an editor, roles or change history. Your editor works in a ready-made panel while you consume the result.
