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