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 list of detected technologies, each with a name, category (e.g. JavaScript framework, CMS, CDN, analytics), version (if detectable), confidence score, and supporting evidence. Covers frontend frameworks, backend technologies, CMS platforms, analytics, advertising tools, CDNs, and more.
Example use cases
Competitor tech stack reconnaissance
“I want to know what frontend framework and analytics tools my competitor acme.com is using — scan their site and give me everything with confidence levels.”
Lead enrichment for sales outreach
“For the lead domain bigcorp.io, figure out what ecommerce platform and CMS they're running so I can tailor our sales pitch accordingly.”
Monitoring stack changes over time
“I previously scanned stripe.com on 2024-11-01 and found React, Next.js, and Segment — can you re-scan it now and tell me if anything has changed in their tech stack?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/react?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, no-signup technology fingerprinting with confidence scores and evidence, especially in automated pipelines where paying micro-amounts per scan (via x402/USDC) is preferable to managing API keys or subscriptions. It is well-suited for lead enrichment, competitive intelligence, or monitoring tech stack drift on a set of domains. Prefer alternatives if you need bulk/batch scanning at scale or require deep JavaScript rendering for SPA detection.
Side effects
- URL is unreachable or returns non-200 response — detection may be partial or empty
- Private or bot-protected sites may block scanning, reducing coverage
- Low-confidence hits returned for heavily obfuscated or minified stacks
- Malformed URL input causes request rejection
- Newly released or niche technologies may not be in the signature set
