Endpoint
POSThttps://cerwal.vercel.app/api/brokenWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use broken link checker that requires no subscription or API key setup — just USDC payment via x402. Best for one-off or infrequent link audits on individual pages rather than full-site crawls.
Side effects
- Invalid or unreachable URL returns error or failed success flag
- maxLinks set too low may miss broken links further down the page
- Payment failure via x402 prevents request from completing
- The /api/broken path may itself be broken or misconfigured given the suspicious endpoint name
- Timeout if the target page is slow to load
- Rate limiting or anti-bot measures on the target site may block crawling
