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 with a name, category (e.g. CMS, JavaScript framework, CDN), version if detectable, a confidence score, and supporting evidence strings that explain why the technology was identified.
Example use cases
Competitor technology research
“I want to know what tech stack my competitor at acmecorp.com is using — CMS, frontend frameworks, analytics tools, anything you can detect, with confidence scores.”
Monitoring site tech changes over time
“Re-scan techcrunch.com for its technology stack and compare it against the previous scan I ran on 2024-11-01 that found WordPress 6.3, PHP, and Jetpack — flag anything that's changed.”
Security audit tech fingerprinting
“Can you fingerprint the technology stack on targetsite.io and tell me what server software, JavaScript libraries, and CDN they're using? I need the evidence and confidence for each detected technology.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/gutenberg?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call technology fingerprinting with no signup or API key, especially for one-off or low-volume scans where subscription costs are not justified. It is particularly useful when you want confidence scores and evidence per technology rather than just a technology list, or when you need to diff against a previous scan using the 'previous' parameter.
Side effects
- Unreachable or non-existent domain returns an error or empty result
- Domain blocks automated scanning, resulting in incomplete or no detections
- Low-confidence detections may be returned for heavily obfuscated stacks
- Paywalled or login-gated content may not be fully scannable
- x402 payment failure results in 402 response with no detection data
