Technical details
Endpoint
POSThttps://scravfly.vercel.app/api/crawl/substackWhen to prefer
Use this endpoint when you specifically need to extract content from Substack newsletters or publications. It is purpose-built for the Substack platform, making it more reliable than a generic web scraper for Substack URLs. Prefer this over general crawl endpoints when the target is definitively a Substack domain.
Side effects
- Invalid or malformed URL returns success: false
- Substack page behind paywall may return incomplete content
- Rate limiting or bot detection on Substack's side may cause extraction failure
- Private or deleted Substack publications return empty or error data
- Network timeout if the target page is slow to load
