How this service works
One bounded batch uses the existing technology detector with a fresh fetch per domain. Reports additions, removals and version changes only when a caller supplies a previous snapshot. First scans have changes=null. Root HTTPS URLs only. Caller snapshots are not authenticated historical evidence. No background jobs, shared history, callbacks or inferred installation dates. Fixed price for a batch of one to three domains.
Output
Returns a structured list of technologies detected for each submitted domain, including the technology name, category (e.g. CMS, CDN, JavaScript framework, analytics), version (if detectable), a confidence score indicating detection certainty, and supporting evidence for each hit.
Example use cases
Competitive tech stack research
“Can you scan hubspot.com, salesforce.com, and marketo.com and tell me what technologies each one is using, with confidence scores? I want to know their CMS, analytics, CDN, and any notable frameworks.”
Sales lead technology profiling
“I'm prospecting a new client at acme-corp.com — can you detect their full technology stack so I know what platforms they're already on before my call?”
Ongoing tech stack change monitoring
“Last week you told me that shopify.com was using React and Google Analytics. Can you re-scan it now and flag anything that's changed in their tech stack?”

Endpoint
POSThttps://stack.halowerk.com/stack/monitor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call, no-signup technology fingerprinting for up to 3 domains at once with confidence scores and evidence — ideal for agents doing competitive research, lead enrichment, or change monitoring without a long-term subscription commitment. Prefer it over scraping-based alternatives when structured, categorized tech stack output with confidence levels is needed, and the x402 micropayment model fits your cost structure.
Side effects
- Invalid or non-HTTPS URL format causes rejection per schema pattern constraint
- More than 3 URLs submitted triggers a validation error
- URL is unreachable or returns non-standard responses, resulting in no technologies detected
- Domain exists but has no detectable technology signals (e.g. plain HTML with no fingerprints)
- Previous scan data malformed or missing required fields causes request rejection
- Payment failure over x402 protocol results in 402 response and no scan performed
