Get every post from any Substack newsletter — including the ones on their own domain, like www.lennysnewsletter.com — as clean JSON: title, subtitle, date, likes, comments, restacks, word count, free or paid, tags, cover image, and optionally the text. Schedule it with Only new posts and each run returns just what was published since the last one.
Don't know which newsletters to watch? Pick a category (Technology, Finance, Food & Drink, …) and it takes the top newsletters from Substack's own category ranking, then their posts. Finding them is free.
What you get
| Field | What it is |
|---|---|
publication, title, subtitle, url, postedAt | the post |

isNewSinceLastRun | true when the post was published after the newest post of your previous run |
Reader comments are not collected.
Fixed 22 Oct 2026: a post counted as new when the previous run had simply not reached it (it stopped at max posts), so with Only new posts a second run could return older posts as new and charge for them. New now means published after the newest post the previous run saw.
Use it for
- Newsletter research — what a competitor or a whole niche publishes, how often, and what gets the most likes and comments
- Content monitoring — a daily feed of new posts from a list of newsletters into a sheet, Slack or your own database
- AI and RAG — clean post text for summaries, search or training your own assistant on newsletters you follow

Pricing
$0.80 per 1,000 posts, or $1.50 per 1,000 posts with text, plus $0.01 per run. Error rows and posts left out by your filters are free. The $0.01 run-start fee is the one charge every run pays, even one that returns nothing.
For AI agents
{"publications": ["platformer"], "maxPostsPerPublication": 10} returns the 10 newest posts with likes and comments. Rows have type: post or error. {"categories": ["Science"], "maxPublicationsPerCategory": 10, "maxPostsPerPublication": 1} gives the latest post of the top 10 science newsletters.
