# Post Index

> Editorial archive with one line per post under sticky year labels, plus search and category chips. On a mouse, hovering a row dims the rest while its cover trails the pointer on a spring, tilting with speed and flipping sides near the edge; keyboard focus pins the preview beside the row. Small screens show an inline thumbnail instead.

Other props pass through to the root element.

| Prop | Type | Default | Description |

## 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/post-index/post-index.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/post-index
```

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

## Code

> Component source needs an Assembli subscription ($12/month or $96/year) and an API key sent as `Authorization: Bearer <key>`. 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. Or subscribe at https://www.assembli.design/pricing and create a key at https://www.assembli.design/account.
