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, each with its name, category (e.g. 'CMS', 'Analytics', 'CDN'), version if detectable, a confidence score, and the evidence signals that triggered the detection. The endpoint returns this for every technology fingerprinted on the target domain.
Example use cases
Competitive tech stack research
“Can you scan shopify.com and tell me every technology you detect — what e-commerce platform, frontend framework, CDN, analytics tools — with confidence levels for each?”
Monitor stack changes over time
“Last week you told me stripe.com was using Next.js and Segment. Scan it again now and flag anything that's changed since then.”
Sales lead enrichment by tech stack
“I'm prospecting hubspot.com — what customer support, CRM, and marketing automation tools can you detect on their site? I need the technology names and categories.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/intercom?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 in agent workflows where you want to detect technologies on arbitrary domains programmatically and pay per call in USDC via x402. It is particularly useful when you also want to diff against a previous known technology snapshot to detect stack changes over time.
Side effects
- Domain unreachable or DNS failure — no technologies returned, error indicating site unavailable
- Invalid or malformed URL input — 400-level error
- Payment failure or insufficient USDC balance — x402 payment required response before results delivered
- Domain returns no detectable signals — empty or low-confidence technology list
- Rate limiting or bot-blocking by the target site — partial or empty results
