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 technologies detected on the target domain, each entry including the technology name, category (e.g. JavaScript framework, CDN, CMS), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitor tech stack research
“I'm doing competitive research — can you scan shopify.com and tell me every technology it uses, what category each falls under, and how confident the detection is?”
Monitor site for tech changes
“We last saw notion.so using these technologies as of 2024-06-01: [{"name":"React","category":"JavaScript Framework","version":"18"}]. Can you re-scan notion.so now and tell me if anything has changed?”
Verify Angular usage on a client site
“My client claims their site myapp.example.com is built with Angular — can you scan it and confirm whether Angular is actually detected, with evidence?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/angular?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-as-you-go technology stack detection without API key signup overhead, especially when integrating into automated pipelines or agent workflows that require USDC-based micropayments via x402. Ideal for one-off scans, competitive research, or change-detection workflows where you pass previous observations to diff against.
Side effects
- URL is unreachable or returns non-200 — detection may fail or return empty results
- Domain blocks automated scanning — partial or no results returned
- Technology is obfuscated or minified beyond fingerprinting — low confidence or missed detections
- Invalid or malformed URL input — request rejected
- Payment failure via x402 — call not processed
