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 on the target domain, each with a name, category (e.g. CMS, JavaScript framework, analytics), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitive tech stack research
“I want to know what technology stack my competitor acme.com is running — frameworks, analytics, CDN, everything — so I can benchmark our own setup against theirs.”
Checking for Matomo analytics adoption
“Does shopify-store.com have Matomo installed? I need to confirm whether they're using Matomo analytics before we pitch them our Matomo consulting services.”
Security audit pre-screening
“Before we start our security assessment of client-portal.io, can you detect all the technologies running on it so we know what to focus on during the audit?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/matomo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need no-signup, pay-as-you-go technology fingerprinting for arbitrary domains, especially when integrating into automated pipelines or agent workflows where API key management is a friction point. The x402 USDC micropayment model makes it ideal for sporadic or high-volume programmatic use without subscription overhead. The optional `previous` input allows incremental/differential detection to track stack changes over time.
Side effects
- URL is unreachable or returns non-2xx status — detection may return empty or partial results
- Domain blocks scanners via robots.txt or rate limiting — reduced detection coverage
- URL malformed or exceeds 2048 characters — request rejected
- Previous observations object missing required fields — validation error
- Unknown or very new technology stack not in fingerprint database — missed detections
- Payment failure via x402 — call not executed
