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 for the given domain, each entry including the technology name, category (e.g. CMS, CDN, JavaScript framework), version (if detectable), a confidence score, and supporting evidence for the identification. Optionally highlights changes relative to a previously observed snapshot.
Example use cases
Competitor tech stack research
“Find out what technologies example-competitor.com is using — I need to know their frontend framework, backend stack, and any marketing or analytics tools they have installed.”
Sales lead enrichment with tech data
“Before my call with acme-corp.com, can you detect what CMS and e-commerce platform their website is built on so I can tailor my pitch?”
Security audit tech fingerprinting
“I need to fingerprint targetsite.io's technology stack and compare it against what we observed last month — here's what we saw previously: WordPress 6.2, PHP 8.1, Cloudflare. Flag anything that's changed or newly detected.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/oxid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-demand, pay-per-call technology fingerprinting with no account setup or API key management. It is especially suitable for agents that need sporadic or one-off stack detection, want to track technology changes over time using the 'previous' snapshot parameter, or require per-call USDC micropayment billing rather than a subscription. Prefer alternatives if you need bulk batch processing of many domains simultaneously or require deep JavaScript rendering for SPA detection.
Side effects
- Invalid or unreachable URL returns an error or empty technology list
- Payment failure over x402 results in a 402 response with no detection performed
- Highly obfuscated or private sites may return low-confidence or empty results
- Malformed 'previous' snapshot object causes validation errors
- Rate limiting or bot protection on the target domain may reduce detection accuracy
