Superhighway URL Unfurl — Page to Markdown

Use this endpoint when you have a specific URL and need its content as clean markdown for reading, summarizing, or quoting — particularly within an AI agent workflow that already uses Superhighway for web search, keeping all web access on one pay-per-call platform with no subscription required.

• URL is unreachable or returns a non-200 status — likely returns an error object
• Page is behind a paywall or login wall — content may be incomplete or empty
• URL points to a binary file (PDF, image) — markdown output may be empty or malformed
• Rate limit or payment failure — returns 402 if x402 payment not accepted
• Malformed URL input — validation error returned
