Example prompt: Can you scrape the content from this Substack page and give me the structured data — https://example.substack.com/p/my-article-title?

## When to prefer this

Use this endpoint when you specifically need to extract structured content from a Substack URL without setting up auth or subscriptions. It is purpose-built for Substack pages (unlike generic crawlers) and uses pay-per-request USDC pricing via x402, making it ideal for lightweight, one-off or agent-driven newsletter scraping tasks.

## Known failure modes

- Invalid or non-Substack URL returns error or empty data
- Private/paywalled Substack posts may return incomplete data
- URL not reachable or Substack page deleted returns failure
- Payment not processed correctly via x402 results in 402 error
- Malformed URL input causes validation failure
