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 URL, each with a name, category (e.g. CMS, JavaScript framework, analytics), version (if detectable), confidence score, and supporting evidence. May include frontend libraries, backend frameworks, CDN providers, analytics tools, and more.
Example use cases
Competitive tech stack research
“I'm evaluating competitors before choosing our own stack — can you detect all the technologies that stripe.com is running, including their frontend frameworks, analytics, and infrastructure?”
Security audit pre-screening
“Before our penetration test, detect what technologies are running on acmecorp.io so we know what attack surface to focus on — frameworks, libraries, versions if available.”
Monitoring a site for stack changes
“I already know that example.com was running WordPress 6.1 and jQuery 3.6 as of last week — can you re-scan it now and tell me if anything in their tech stack has changed?”
Technical details
Endpoint
POSThttps://stack.halowerk.com/stack/articles/jquery?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go, no-signup technology stack detection for any public URL, especially for one-off lookups or agent workflows where API key management is undesirable. The x402 USDC payment model makes it suitable for automated pipelines. The optional `previous` field makes it ideal for change-detection workflows where you want to compare against a prior scan.
Side effects
- URL is unreachable or returns non-200 — detection may fail or return empty results
- Private/intranet URLs cannot be scanned
- Dynamic single-page apps may obscure some technologies
- Rate-limited or bot-protected sites may yield incomplete results
- Obfuscated or minified code may reduce confidence scores
