Headless

When your frontend is rendered by a separate app (Nuxt, Next, Astro, …) instead of Craft, enable headlessMode. LLMify then generates Markdown by fetching your front-end URLs and exposes it through the API endpoints below, so your frontend can pull the content and re-serve it under its own domain.

Authentication

The API is only available while headlessMode is enabled, otherwise every endpoint returns 403.

Protection with a token is optional:

• No token configured (default): the endpoints are reachable without authentication. The content they expose (llms.txt, page Markdown) is public anyway.
• Token configured via the apiToken setting: every request must send it in the X-Llmify-Token header. Requests with a missing or wrong token return 403.

curl -H "X-Llmify-Token: <your-token>" \
  "https://cms.example.com/actions/llmify/api/llms-txt"

llms.txt

Returns the llms.txt content for a site.

GET /actions/llmify/api/llms-txt?site=<handle|id>

Responses

curl "https://cms.example.com/actions/llmify/api/llms-txt?site=default"

llms-full.txt

Returns the llms-full.txt content for a site. Identical interface to llms.txt.

GET /actions/llmify/api/llms-full-txt?site=<handle|id>

curl "https://cms.example.com/actions/llmify/api/llms-full-txt?site=default"

page

Returns the pre-generated Markdown for a single page, identified by its URI. The response includes front matter, and only pages whose section is enabled are served. This is the recommended way to serve individual .md files, as it reads the stored Markdown without re-converting.

GET /actions/llmify/api/page?uri=<uri>&site=<handle|id>

Responses

curl "https://cms.example.com/actions/llmify/api/page?uri=blog&site=default"

convert

Fetches a front-end URL and returns its converted Markdown on the fly, without persisting it or adding front matter. Use this for ad-hoc conversion; prefer page for serving stored pages.

POST /actions/llmify/api/convert
Content-Type: application/json

{ "url": "https://www.example.com/blog/my-post" }

Responses

curl -X POST "https://cms.example.com/actions/llmify/api/convert" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://www.example.com/blog/my-post"}'

Example Implementation

The llmify-headless-showcase repository shows a complete Nuxt integration: server routes that proxy llms.txt / llms-full.txt, serve individual .md pages via the page endpoint, and inject the discovery <link> tag.
