# Preview a link

`POST https://api.markdrop.in/api/v1/link-preview`

The same as [Preview a bookmark](https://docs.markdrop.in/api/pages/preview-a-bookmark), with limits of its own.

- **Authentication:** API token required: `Authorization: Bearer mdk_…`.
- **Rate limit:** 300 per day, 30 per minute per IP address.

## Request body

`application/json`, required.

- `url` (string, required): The `http` or `https` link to preview. 1–2,048 characters.

## Responses

- `200`: OK.
- `401`: No token, or the token is revoked or mistyped.
- `422`: The request didn't validate. `detail` lists each problem, with where it is (`loc`) and why (`msg`).
- `429`: Too many requests from your IP address. Wait the seconds in `Retry-After`.
