# Article Layout

> A blog post page: breadcrumb, title, standfirst, authors and reading time over a wide cover. The table of contents is built from the post's own headings, pins beside the text, tracks the section you're reading and folds into a menu on phones. A progress bar, a share rail, heading anchors, author bios and related posts frame it, with figure, callout and pull-quote parts for the body.

| `authors` (required) | `ArticleAuthor[]` |  |  |

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/article-layout/article-layout.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/article-layout
```

Registry item JSON: https://www.assembli.design/r/article-layout.json (send `Authorization: Bearer <api key>`)

## Code

To get one without copying anything, POST https://www.assembli.design/api/agent/login (or call the MCP tool connect_account), show the user the link it returns, and poll https://www.assembli.design/api/agent/token for the key.
