Public Substack API client. No auth, no login needed.
Modes
- archive — recent posts list (paginated,
maxItemsto cap) - post — full post by slug (includes body text)
- publication — publication profile + subscriber/post counts
Input
| Field | Type | Description |
|---|---|---|
| publication | string | Substack slug (e.g. a16z) or custom domain |
| mode | enum | archive (default), post, publication |
| maxItems | int | Max posts (0 = all) |
| postSlug | string | Post slug for post mode |
Output
Archive/post rows: id, title, slug, postDate, audience, type, subtitle, url, likeCount, commentCount, wordCount, bodyText (post mode only), publication, mode.
Publication rows: id, name, slug, url, description, subscriberCount, postCount, mode.
Notes
- Custom domains (e.g.
stratechery.com) may redirect/api/v1/*to their own archives — prefer the substack slug when known. - Uses curl (proven TLS fingerprint for WAF'd sites).
