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, CDN, analytics, framework), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitive technology stack audit
“I'm researching our main competitor at shopify.com — can you detect their full technology stack and tell me what frameworks, infrastructure, and marketing tools they're running, with confidence scores?”
Sales prospecting tech qualification
“Before our outreach call, can you scan acme-corp.com and tell me what CMS, e-commerce platform, and analytics tools they're using so we can tailor our pitch?”
Monitoring site stack for changes
“I want to check stripe.com's current tech stack against what we detected last month — we saw React, Node.js, and Fastly back then. Has anything changed?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/braintree?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, no-signup technology detection paid with USDC over x402, especially in agent workflows where API key management is impractical. Ideal for one-off competitive research, CRM enrichment, or programmatic lead qualification without committing to a subscription. The optional 'previous' parameter makes it useful for change-detection workflows comparing current results against a prior scan.
Side effects
- URL is unreachable or returns non-200 — no technologies detected
- Domain blocks crawling or fingerprinting — partial or empty results
- URL malformed or exceeds 2048 characters — validation error
- Payment over x402 fails — request not processed
- Rare or obfuscated tech stacks may yield low-confidence or missed detections
