# Substack Post Bodies API

Up to 50 posts a cursor page, each with its full free body or the public preview of a paid post.

`GET /v1/substack/publications/{publication}/posts/bodies` returns archive posts with their bodies. `publication` is a subdomain, host or URL; a numeric publication id is refused here. `limit` is 1 to 50 and defaults to 20, and `cursor` comes from the previous page's `page.nextCursor`.

`data.posts[]` carries the same post fields as the archive plus `bodyHtml`. A free post has its whole body and `bodyIsPreview: false`. A paid or subscriber-only post has the preview the publication makes public and `bodyIsPreview: true`. `data.page` reports `hasMore` and `nextCursor`. The route is cursor paged because the archive offset does not carry bodies.

## FAQ

### Will I get the full text of a paid post?

No. You get the preview the publication makes public, with `bodyIsPreview: true`. A free post has the whole body and `bodyIsPreview: false`.

### How many posts fit on a page?

Between 1 and 50, with 20 as the default. Follow `page.nextCursor` while `page.hasMore` is true.

### What else is on each post?

The same metadata as the archive: `id`, `title`, `subtitle`, `url`, `publishedAt`, `tags`, `authors`, `commentCount`, `reactionCount`, `restackCount`, `audio` and `video` details when present.

### How many credits does a bodies page cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth.
