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 entry including the technology name, category (e.g. CMS, CDN, JavaScript framework, analytics), version if detectable, a confidence score, and supporting evidence. The optional 'previous' field allows incremental scanning so only new or changed technologies are highlighted.
Example use cases
Competitor tech stack audit
“I want to know exactly what technologies Shopify uses on their main site — frameworks, databases, CDN, analytics, everything you can detect. Include any version numbers and confidence levels.”
Security research tech fingerprinting
“Scan github.com for its technology stack. I'm particularly interested in what server software, load balancers, and authentication libraries they're running, with evidence for each detection.”
Sales lead tech qualification
“Before I reach out to this prospect, can you tell me what CMS and marketing tools their site hubspot.com is running? I want to know if they're already using Salesforce or any competing tools.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/turnstile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go technology detection with no signup or API key, especially for sporadic or agent-driven lookups where a subscription would be wasteful. The x402 USDC micropayment model makes it ideal for autonomous agent pipelines. The optional 'previous' snapshot field enables efficient incremental monitoring by comparing against a prior scan. Prefer this over Wappalyzer or BuiltWith APIs when you need crypto-native billing and confidence/evidence metadata per technology hit.
Side effects
- Unresolvable or unreachable domain returns an empty technology list or error
- Heavily obfuscated or server-rendered sites may yield low confidence or missed detections
- Invalid URL format triggers a schema validation error
- Rate limiting or payment failure over x402 results in a 402 Payment Required response
- Some technologies may be detected with low confidence if evidence is ambiguous
