How this service works
Domain in, technology stack out. Confidence and evidence for every hit. Pay per call in USDC over x402. No signup, no API key.
Output
A structured list of detected technologies for the target domain, each with a name, category (e.g. CMS, JavaScript framework, CDN), version where detectable, confidence score, and supporting evidence for the detection hit.
Example use cases
Competitor tech stack audit
“Can you scan shopify.com and tell me every technology it's using — frameworks, CDN, analytics, payment systems — with confidence scores for each?”
SEO platform detection
“I want to know if moz.com is running Yoast SEO or a competing SEO plugin — scan their tech stack and show me what you find.”
Security posture reconnaissance
“What security technologies and WAF providers does cloudflare.com use? Scan their domain and give me the full breakdown with evidence.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/yoast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go technology stack detection with no API key or signup required, especially for one-off or infrequent lookups billed in USDC via x402. It is well-suited for agents that need to fingerprint arbitrary domains on demand and want per-detection confidence scoring with evidence, rather than a subscription-based bulk crawler.
Side effects
- Domain is unreachable or returns non-200 responses — detection may be incomplete or fail entirely
- Private/intranet domains cannot be scanned from external infrastructure
- Heavily obfuscated or minified stacks may yield low confidence or missed detections
- Invalid URL format returns a validation error
- Rate limiting or bot protection on the target domain may block fingerprinting probes
