Substack

Read Substack publication content, posts, comments, podcast episodes via public RSS/JSON feeds. 5 tools, no auth required.

セットアップ

Setup: NO API KEY. Set SUBSTACK_PUBLICATION_URL = the publication's base URL (e.g. https://lennysnewsletter.substack.com). For tools that target a specific publication, the URL is taken from this env var.

Authentication: NONE. All reads use public endpoints (the same JSON Substack's own site fetches).

Content endpoints available:

  • /api/v1/posts?limit=N&offset=M — paginated posts list (each post: id, title, slug, post_date, audience, type)
  • /api/v1/posts/by-id/{id} — single post detail
  • /api/v1/comments/{post_id} — top comments on a post
  • /api/v1/podcast/feed — podcast episodes (audio newsletters only)
  • /feed — standard RSS feed

…(continued in the in-app connector instructions)
