Substack Search Posts Scraper

Search Substack posts by keyword across every publication. Returns post title, subtitle, author, publication, publication date, engagement (likes, comments, restacks), paywall status, word count, cover image and tags, plus the publications related to the query. Supports a time window from the past day to the past year.

Features

• Real-time Substack data — results are fetched live at run time, never cached or stale
• No login, cookies, or proxy configuration needed — just provide the input and run
• Each result is pushed as a separate dataset item, exportable as JSON, CSV, or Excel
• Fast: a typical run finishes in seconds

Input

Field	Type	Required	Description
query	string	yes	Search keyword (max 500 characters)
page	integer	no	Page number for pagination (1-101). Each page returns 16-20 posts.
posted_ago	string	no	Only return posts from this period: 24h (past day), 7d (past week), 30d (past month), or 12m (past year). Omit for all time. Any other value returns 400. One of: 24h, 7d, 30d, 12m.
language	string	no	Two-letter language code, e.g. es, to rank posts in that language first

Pricing

This Actor is billed per run — a flat $0.003 per run.

• One run returns all matching results for your input, and costs $0.003 — whether it comes back with one result or hundreds.
• You’re only charged when a run succeeds, or when it fails because what you asked for was looked up and doesn’t exist, is private, or isn’t valid: that costs one run ($0.003). Other failed runs are free.
