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
Returns a structured list of detected technologies for the given domain, each with a name, category (e.g. CMS, CDN, analytics, framework), version if detectable, a confidence score, and supporting evidence. May also flag technologies no longer detected compared to a previously observed baseline.
Example use cases
Competitor tech stack audit
“Scan shopify.com and tell me everything you can detect about their technology stack — frameworks, CDN, analytics, and anything else — with confidence scores for each technology found.”
Sales lead technology enrichment
“I have a prospect at hubspot.com — can you detect what technologies they're running so I know what tools they already use before I pitch them?”
Security and compliance stack check
“Run a technology detection scan on stripe.com and tell me if they're using any known third-party analytics or tracking libraries, with evidence for each one you find.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/calendly?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go technology fingerprinting with no API key or subscription required — ideal for one-off lookups, agentic workflows, or enriching CRM/sales data on demand. Particularly useful when you want confidence scores and evidence per technology rather than just a yes/no result. The optional 'previous' snapshot field makes it well-suited for change-detection workflows where you want to diff the current stack against a known baseline.
Side effects
- Invalid or unreachable URL returns an error or empty technology list
- Domain blocks automated scanning, resulting in partial or low-confidence results
- x402 payment failure causes request rejection before analysis begins
- Malformed 'previous' object (missing required fields) causes validation error
- Rate limiting or network timeouts on the target domain may reduce detection accuracy
