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. CDN, CMS, JavaScript Framework), version if detectable, a confidence score, and supporting evidence. Results reflect the current observable tech fingerprint of the target URL.
Example use cases
Competitor tech stack research
“I want to know what technologies stack.halowerk.com's competitor keycdn.com is built on — dig into their frontend, backend, CDN, and analytics tools.”
Sales lead technology enrichment
“Before my sales call, can you check what tech stack Shopify.com is running so I know which integrations to pitch?”
Monitor site for tech changes
“I scanned example.com last week and found React and Nginx — can you re-scan it now and tell me if anything in the stack has changed since then?”

Endpoint

Choose this endpoint when you need no-signup, pay-per-call technology fingerprinting of a web domain with structured, categorized output including confidence scores. It is ideal for one-off lookups, agent-driven competitive intelligence, or enriching CRM/lead data without a subscription. It also supports incremental scanning by accepting a previous scan payload to detect changes over time.
Side effects
- Invalid or unreachable URL returns an error or empty technology list
- Payment failure via x402 blocks the request
- Domain with heavy bot protection may return incomplete or no detections
- Malformed 'previous' object schema causes a validation error
- Very new or obscure technologies may not be recognized, resulting in low-confidence or missing entries
