主要エンドポイント
/substack/categoriesReturns every public Substack category, with the category id required by /substack/category. Ids span two spaces: 32 categories use a numeric id and one uses the string id `podcast`. Both are accepted by /substack/category.
MCPツール substack_categories
/substack/categoryReturns one page of a category's public publication leaderboard. Each row carries the publication's subscriber signals and its full subscription offering (web plans with multi-currency pricing, App Store plans, and per-tier benefits). Subscriber totals are published to roughly three significant figures and are opt-in per writer; paid subscriber figures are only ever buckets. Upstream serves 25 publications per page and accepts pages 0-26, so at most 675 publications are reachable per category and type.
MCPツール substack_category
/substack/exploreReturns one page of Substack's Explore surface. Explore is a feed of heterogeneous modules rather than a flat list, so each page returns the modules it contains and every module names its own type. Known module types are `trendingTopicsExplore` (trending topics and suggested searches), `trendingPostsExplore`, `newBestsellersExplore`, `videoSuggestionsExplore`, `categoryLeaderboard`, `comment` (a single Note) and `post` (a single post). Only the collections a module actually carries are populated. Pagination is cursor-based; early pages are curated shelves and later pages are individual Notes and posts.
MCPツール substack_explore
/substack/leaderboardReturns one page of a category's bestseller leaderboard, pairing each ranked publication with its author. This is a different surface from /substack/category: it exposes the trending ranking (the site's "Rising" tab), validates its ranking values rather than silently defaulting, accepts the extra cross-category id `bestseller`, and returns the author alongside the publication. Use a category_id from /substack/categories whose in_leaderboard is true. Upstream serves 25 rows per page and accepts pages 0-25.
MCPツール substack_leaderboard
/substack/noteReturns one public Note with its author, engagement counts, and the post it links to when it has one. Notes are Substack's short-form social posts. note_id is the numeric id from a Note URL: in `/@handle/note/c-316240438` it is `316240438`.
MCPツール substack_note
/substack/note/repliesReturns one page of public replies to a Note, each in the same shape as /substack/note. Pagination is cursor-based: pass the previous response's next_cursor back as cursor.

Substackのスクレイピング方法
Crawlora's 19 Substack endpoints cover discovery (categories and leaderboards), publications (profile, subscription plans, post archive, contributors, and recommendations), individual posts and Notes with their reply and restack threads, site-wide search, and writer profiles with their activity and connections — all normalized JSON with one API key, no Substack account required.
Call /substack/categories for the full category list, each row flagged for whether /substack/category or /substack/leaderboard accepts it. Pass a category_id to /substack/category for a paid or free subscriber-count ranking (25 publications per page, pages 0-26), or to /substack/leaderboard for the trending, paid, or all-time bestseller ranking with each publication's author attached.
/substack/notes/tabs lists every selectable tab for the feed and explore surfaces. Pass a tab and its type to /substack/notes for the public Notes feed, or to /substack/explore for Substack's heterogeneous Explore surface — trending topics, trending posts, new bestsellers, and category leaderboards, paged with a cursor.
Pass a subdomain, custom domain, or numeric publication_id to /substack/publication for its profile and complete subscription offering — every web and App Store plan, benefits, and subscriber counts. /substack/publication/posts returns its public post archive, /substack/publication/contributors its credited writers, and /substack/publication/recommendations the publications it recommends to readers.
/substack/post takes a publication and slug for one post's extended metadata, including word count and every credited byline. /substack/note takes a numeric note_id for one public Note, Substack's short-form social post, with its reaction, reply, and restack counts; /substack/note/replies and /substack/note/restacks page through its reply thread and its reshares.
/substack/search finds posts and publications across all of Substack; /substack/user/search finds writer profiles by name or handle. /substack/user returns one writer's public profile, /substack/user/activity their public notes, posts, likes, replies, and restacks, and /substack/user/connections their followers, following, or subscribers.
FAQ
Not indefinitely — /substack/category and /substack/leaderboard both serve exactly 25 publications per page and cap out at page 26 and 25 respectively, so at most 675 publications are reachable per category per ranking type. To go further, walk /substack/publication/contributors or /substack/publication/recommendations outward from a seed publication instead of paging.
No — /substack/post and /substack/publication/posts return metadata only: title, url, audience, word count, credited bylines, and engagement counts, never post bodies. paywalled is derived from the audience field.
Notes are Substack's short-form social posts — internally modeled as comments, which is why their ids look like comment ids. /substack/note returns one Note with its reaction, reply, and restack counts; /substack/note/replies pages its reply thread and /substack/note/restacks pages the Notes that reshared it, which can carry their own commentary or be a bare reshare.
Inconsistent by design — publications and writers opt in separately. total/total_display is opt-in and total_hidden marks a writer who hid the count rather than having zero subscribers; paid_rough and paid_tier are the only paid-subscriber signals, both bucketed, since Substack publishes no exact paid count on any public surface.
Yes — /substack/publication/posts is scoped to one publication's own archive, while /substack/search is the site-wide counterpart. Passing a focus_publication_id to /substack/search additionally returns that one publication's own matching posts (focused_posts) alongside the site-wide results.
