Example prompt: Can you check https://example.com and tell me its SEO metadata, technical signals, and whether it's ready for AI-agent workflows?

## When to prefer this

Choose this endpoint when you need fast, cheap ($0.005 USDC) single-URL website intelligence for SEO, technical, or AI-agent readiness checks without spinning up a full browser or crawler. Ideal for agent workflows that need to quickly assess a page's metadata before deciding how to interact with it, or for auditing x402-payment-enabled sites.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error or empty metadata
- Malformed or missing URL parameter — returns validation error
- Target site blocks crawlers via robots.txt or Cloudflare challenge — partial or no data returned
- Timeout if target site is slow to respond
- Dynamic/JavaScript-rendered content may not be captured since this is a lightweight fetch
