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
A structured list of detected technologies on the target domain, each entry including the technology name, category (e.g. CMS, CDN, JavaScript framework, analytics), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitor tech stack audit
“I want to know what technologies my competitor acme.com is running — frontend frameworks, backend stack, analytics, CDN, everything you can detect. Give me confidence scores too.”
E-commerce platform identification
“Can you check whether techcrunch.com is running on Shopify, WordPress, or something else, and list all the tools and plugins you can detect on their site?”
Monitoring stack changes over time
“Last week I scanned stripe.com and found it was using React, Next.js, and Cloudflare. Can you scan it again now and tell me if anything in their tech stack has changed?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/shopify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, confidence-scored technology detection for a specific domain without signing up or managing API keys. Ideal for one-off or programmatic per-domain lookups billed per call in USDC. The optional 'previous' input makes it especially useful for change-detection workflows where you want to diff the current stack against a known baseline.
Side effects
- Invalid or unreachable URL returns an error with no technology data
- Domain blocks automated scanning, resulting in partial or empty detections
- Unknown or proprietary technologies may not be recognized
- Payment failure via x402 prevents the call from completing
- Rate limiting or bot protection on the target domain may reduce detection accuracy
