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, framework, CDN, analytics), version if detectable, a confidence score, and supporting evidence. May optionally compare against a previously observed snapshot to highlight changes.
Example use cases
Competitor ecommerce platform research
“What ecommerce platform and frontend framework is my competitor myshop.com using? I want to know their full tech stack with confidence scores.”
Sales lead enrichment for SaaS outreach
“Before I reach out to acme.io, can you detect what software they're running on their site so I know which products to pitch?”
Security audit pre-scan recon
“I'm doing a security assessment on example.com — can you fingerprint their technology stack and flag all detected server-side frameworks and libraries?”

Endpoint

Choose this endpoint when you need per-call, no-signup technology fingerprinting of a domain with structured confidence and evidence output, paid in USDC via x402. Ideal for agents that need on-demand stack detection without managing API keys or subscriptions. The optional 'previous' snapshot parameter makes it especially useful for change-detection workflows.
Side effects
- URL unreachable or returns non-200 — no technologies detected
- Domain has strong bot/fingerprint protection — low confidence or empty results
- Invalid URL format — request rejected
- Rate limits or x402 payment failure — call not processed
- Previously observed snapshot malformed — ignored or error returned
