Technical details
Endpoint
GEThttps://api.x402node.dev/web/headersWhen to prefer
Use this endpoint when you need a quick, automated security header audit for any public URL, especially for compliance checks, security reviews, or when building dashboards that track header hygiene across multiple sites. Prefer this over manual browser inspection or full vulnerability scanners when you only need header-level analysis.
Side effects
- Invalid or unreachable URL returns an error with no headers or score
- Timeout if the target server is slow to respond
- Non-HTTPS URLs may lack HSTS by design, reflected in low score
- Redirects may result in headers from the final destination, not the original URL
