SUBSTACK ARCHIVER // WAYBACK MACHINE PIPELINE

Archive a Substack

Fetches all published posts via the Substack API and submits each to the Wayback Machine. Skips URLs archived within the staleness window unless forced.

Re-archive after
Day‑based options compare the current date against the last archive date. “Only if content has changed” ignores the time window and re‑archives only when Substack metadata indicates the post has been updated since the last archive.
