How this service works
Inspect security, cache, redirect, and server headers to audit a URL quickly.
Output
A structured report of the HTTP response headers returned by the target URL, categorized into security headers (e.g. HSTS, CSP, X-Frame-Options), cache directives, redirect signals, and server identity headers, enabling quick security and compliance auditing.
Example use cases
Example prompt
“Can you inspect the HTTP response headers for https://example.com and tell me what security, cache, redirect, and server headers it's returning so I can audit it?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/http-headers-inspectWhen to prefer
Use this endpoint when you need a fast, structured audit of HTTP response headers for a specific URL — especially for security posture checks (HSTS, CSP, X-Frame-Options), cache policy review, redirect chain inspection, or server fingerprinting. Prefer it over full site crawlers when only header-level intelligence is needed without body content.
Side effects
- URL is unreachable or times out — returns an error with connection details
- Invalid or malformed URL input — returns a validation error
- Target server returns no headers or blocks the request — partial or empty header report
- DNS resolution failure for the given URL — returns a DNS error
- Non-HTTP/HTTPS URL provided — returns an unsupported scheme error
