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 detected technologies for the given domain, each including the technology name, category (e.g. CMS, analytics, CDN), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitor tech stack reconnaissance
“Can you scan shopify.com and tell me every technology you detect — frameworks, analytics, CDN, payment tools — with confidence levels for each?”
Verify if a site uses a specific tool
“Does acmecorp.com have tawk.to live chat installed? Scan it and tell me if you detect it with evidence.”
Monitor stack changes over time
“Last week you told me example.com was running WordPress and Google Analytics. Can you scan it again now and flag anything that's changed in their tech stack?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/tawkto?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go technology fingerprinting with no API key or signup, particularly for one-off or infrequent lookups. It is well-suited for agent workflows that need to enrich domain records with stack data on demand, or monitor a specific site for tech stack changes using the `previous` snapshot parameter. Prefer it over heavier competitive intelligence platforms when per-call USDC micropayments are acceptable and you need structured, evidenced output per technology hit.
Side effects
- URL is unreachable or returns non-200 response — technology list may be empty or partial
- Domain uses heavy bot protection (Cloudflare, etc.) — detection may be incomplete
- Invalid or malformed URL input — request rejected
- Payment failure over x402 — call not processed
- Site uses server-side rendering only — client-side technologies may not be detected
