Technical details
Endpoint
POSThttps://cr4vvol.vercel.app/api/substackWhen to prefer
Use this endpoint when you need to extract content or metadata from a specific Substack URL without setting up authentication or subscriptions. It is ideal for one-off or infrequent Substack scraping tasks where pay-per-request pricing ($0.02 USDC) is preferred over a recurring subscription. Choose this over general-purpose scrapers when you specifically need Substack-optimized extraction.
Side effects
- Invalid or non-Substack URL returns an error or empty data object
- Private or paywalled Substack posts may return incomplete content
- Network timeout if the Substack page is slow or unavailable
- Malformed URL input causes a 400-level error
- Payment failure via x402 prevents the request from being processed
