Scrape any Substack newsletter or publication archive in one shot.

Multi-publication batch, direct Substack API, no JavaScript rendering, no captchas. Returns posts, podcasts, videos with the engagement metrics that matter (reactions, comments, restacks, wordcount).

$0.004 / post — cheaper than per-platform-call alternatives.

Pricing

$0.004 per post. No actor-start fee.

Free Apify plan: 20 posts per run.

How it works

• Calls https://{publication}/api/v1/archive?sort={sort}&offset={offset}&limit=12 — the same API the public Substack website uses to render the archive page.
• got-scraping handles TLS fingerprinting (no rate limit on reasonable usage).
• Stops when an empty page is returned or maxItems reached. Hard safety cap at offset 2000.

Caveats

• Paid-only posts (audience: only_paid) are returned but with truncated body / no full text — Substack only exposes the metadata publicly. Use a logged-in scraper if you need full paid content.
• The archive API skips posts older than the publication's archive_limit setting (rare; most publications don't set one).
