/substack/posts/search

💡 AI Hint: List or keyword-search posts of a single Substack publication. publication is the publication’s subdomain (e.g. platformer) or custom domain (e.g. thefp.com). Set search to filter posts by a keyword, omit it to get the plain feed. sort orders the feed (new/top/community). Each item is a post projection (id, alias, title, subtitle, preview_text, audience, type, published_at, reaction_count, comment_count, image) — use substack/posts with the alias to fetch the full post body.
