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, each with a name, category (e.g. CMS, CDN, JavaScript framework), version if detectable, a confidence score, and supporting evidence for how the technology was identified on the target domain.
Example use cases
Competitor tech stack audit
“I want to know exactly what technologies stack.halowerk.com's articles section is running — CMS, frameworks, analytics tools, CDN, all of it, with confidence levels for each one.”
SEO plugin detection for leads
“I'm prospecting sites that use RankMath for SEO — can you check rankmath.com and tell me if it's actually using RankMath itself, and what else is in its stack?”
Monitoring stack changes over time
“Check the tech stack on rankmath.com again and compare it against what we saw last week — has anything changed, like a new CDN, framework version, or plugin?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/rankmath?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, per-domain technology fingerprinting with confidence scoring and evidence — especially useful for competitive intelligence, lead scoring by tech stack, SEO tooling audits, or change-detection workflows. It requires no API key or signup and bills per call in USDC via x402, making it ideal for agent-driven, on-demand lookups without subscription overhead. Prefer it over bulk crawlers when you need structured, evidence-backed results for individual domains.
Side effects
- Invalid or unreachable URL returns an error with no technology results
- Payment failure via x402 results in a 402 response and no data returned
- Domain with heavy bot protection may yield partial or empty results
- Malformed input schema (e.g. missing required fields in 'previous') returns a validation error
- Rate limiting or upstream probe failures may return incomplete stack data
