Meet ProbeDeck
One endpoint, every signal. Hit any URL — get back WHOIS, DNS, SSL state, HTTP headers, detected tech stack, favicon and meta in a single REST call. Built for developers, distributed via RapidAPI Hub.
What it does
A single GET call returns a structured JSON document with everything we know about the target. No chaining four APIs and merging fields yourself.
Registrar, creation/expiry, name servers, full record set, certificate chain with issuer, validity window and DNSSEC status.
Security headers, CSP, HSTS — plus fingerprinting that names the CMS, framework, analytics and CDN behind the response.
Site icon as Base64 or URL, OG tags, Twitter cards, canonical URL — everything a directory or scraper needs in one call.
Aggressive caching where it makes sense — fresh probes where it doesn’t. P50 under 400 ms, P99 under 1.5 s for cached lookups.
Targets resolved before the request leaves the box. Private ranges, loopback, link-local and metadata endpoints rejected automatically.
