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 structured list of detected technologies for the given domain, each entry including the technology name, category (e.g. CMS, CDN, analytics, framework), version if detectable, a confidence score, and supporting evidence for the detection.
Example use cases
Competitive tech stack research
“I'm researching our competitor stripe.com — can you scan their domain and tell me every technology they're running, including their frontend framework, backend infrastructure, and any third-party tools, with confidence levels for each?”
Sales lead enrichment with tech data
“I have a list of SaaS companies I'm targeting — can you detect the technology stack for shopify.com so I know whether they're a good fit for our developer tool before I reach out?”
Monitoring site tech stack changes
“Can you scan notion.so for its current technology stack? I checked it three months ago and found they were using Next.js version 12 and Cloudflare — I want to see if anything has changed since then.”
Technical details
Endpoint
POSThttps://stack.halowerk.com/stack/articles/mollie?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call, no-signup technology stack detection with confidence scoring and evidence — particularly useful for agents doing competitive intelligence, sales enrichment, or monitoring technology changes over time. The optional 'previous' parameter makes it well-suited for change-detection workflows where you want to diff a new scan against a prior observation. Prefer this over browser-based Wappalyzer-style tools when you need a programmatic, API-native, micropayment-friendly solution with no API key management.
Side effects
- Invalid or unreachable URL returns an error with no technology data
- Domain blocks scanning tools, resulting in incomplete or empty technology list
- Low-confidence detections may return partial results with uncertain evidence
- Rate limits or payment failures over x402 result in a 402 Payment Required response
- Malformed input schema (missing required fields) returns a validation error
