## When to prefer this

Choose this endpoint when an AI agent needs to extract text content, links, or basic SEO metadata from a single public URL on a pay-per-call basis with no account setup. It is ideal for agents that need lightweight, stateless web content access with USDC micropayments via x402, avoiding the overhead of registering for traditional scraping APIs.

## Known failure modes

- Non-public or paywalled URLs return empty or incomplete content
- URLs returning non-HTML content (PDFs, binaries) may not parse correctly
- Network timeouts if the target URL is slow or unreachable
- Malformed or invalid URLs result in an error response
- JavaScript-rendered pages may return incomplete text if server-side rendering is absent
