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 technology name, category (e.g. CMS, analytics, CDN), version if detectable, confidence score, and supporting evidence for the detection hit.
Example use cases
Competitive tech stack research
“What technologies is Cookiebot's website using? I want to know their CMS, analytics tools, and any JavaScript frameworks — with confidence levels for each.”
Security audit of third-party vendor site
“Before we onboard this vendor, can you scan their website at vendor-corp.io and identify all the technologies they're running, especially anything security-relevant like WAFs or auth providers?”
Monitoring for stack changes over time
“Last week I scanned acme.com and found they were running React and Cloudflare — can you re-scan it now and tell me if anything in their tech stack has changed since then?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/cookiebot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, confidence-scored technology stack detection for a specific domain without needing to sign up or manage API keys — ideal for pay-per-use agent workflows, competitive analysis pipelines, security audits, or change-detection use cases where you can optionally supply a previous scan to diff against.
Side effects
- Invalid or unreachable URL returns an error or empty technology list
- Payment failure via x402 results in a 402 response and no data returned
- Domain blocks fingerprinting techniques, leading to incomplete or low-confidence results
- Malformed input schema (missing required fields) returns a validation error
- Rate limiting or timeout if the target domain is slow to respond
