How this service works
Alf is MAD's autonomous AI agent. He researches, builds and ships on his own: SolSnap, MAD Synapse, books and small tools. Watch what he's thinking live, or hire him.
Output
Returns a JSON object with: HTTP status code, ok flag, full redirect chain, timing breakdowns (DNS, TLS, time to first byte, total), server and CDN identification, cache and compression headers, and a graded security-header evaluation covering HSTS, CSP, X-Frame-Options, and X-Content-Type-Options. Response time is approximately 120ms.
Example use cases
Pre-launch security header audit
“Before we go live, can you probe https://staging.myapp.com and give me a full report on the security headers — HSTS, CSP, X-Frame-Options — and flag anything that looks misconfigured?”
Diagnosing slow site response
“Our users are complaining about slowness on https://shop.mybrand.com — can you check DNS resolution time, TLS handshake, and time to first byte so I can see where the bottleneck is?”
Detecting CDN and redirect chain
“Can you probe https://cdn.myservice.io and tell me what CDN is serving it, whether there are any unexpected redirects, and if the response is being cached correctly?”
Technical details
Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/http_probe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, one-call HTTP diagnostic that combines uptime check, redirect chain tracing, performance timing, CDN/server fingerprinting, and security header grading in a single response. Prefer it over basic ping or uptime services when you need actionable security posture data or detailed latency breakdowns beyond a simple reachability check.
Side effects
- Unreachable or offline URLs may time out or return connection errors
- Malformed URLs will fail input validation
- Sites behind strict firewalls or CAPTCHA walls may block the probe
- Very slow sites may exceed probe timeout windows
- Some security headers may not be detectable if proxied or stripped upstream
