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 for the target domain, each with a name, category (e.g. 'CMS', 'CDN', 'JavaScript Framework'), version where detectable, confidence score, and supporting evidence. May also include metadata about when the detection was performed.
Example use cases
Competitive tech stack research
“I'm researching our competitors — can you tell me what technologies stripe.com is built on, including their frontend frameworks, CDN, and any analytics or A/B testing tools you can detect?”
Sales lead enrichment by tech stack
“I need to qualify a sales lead — can you check what ecommerce platform and payment provider shopify.com is using so I can tailor my outreach?”
Ongoing stack change monitoring
“I tracked that shopify.com was using React and Cloudflare as of last month — can you re-check now and tell me if anything in their tech stack has changed since then?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/adyen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, no-signup technology stack detection paid in USDC via x402, especially for one-off lookups or agent workflows that don't justify a recurring SaaS subscription. It is particularly useful when you want confidence-scored, evidence-backed results and optionally want to diff against a previously observed snapshot to detect stack changes over time.
Side effects
- Domain unreachable or returns non-2xx — detection may be incomplete or fail entirely
- Payment failure over x402 — call is not executed if USDC payment is rejected
- Domain blocks scraping or fingerprinting — reduced confidence or missing technologies
- Invalid URL format — request rejected with validation error
- Rate limiting or bot protection on target site — partial results returned
