Notes

Paid articles: Articles marked as "only_paid" may only return a preview of the body content.
Rate limiting: The Actor adds a 500ms delay between API requests to avoid overloading Substack servers.
Custom domains: Both newsletter.substack.com and custom domains like platformer.news are supported.
No authentication required: Uses Substack's public API endpoints.

Cost

This Actor uses only HTTP API calls (no browser), so it's very lightweight:

~256MB memory is sufficient
No proxy required
A typical run of 50 articles completes in under a minute
