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 list of detected technologies for the given domain, each entry including the technology name, category (e.g. CDN, CMS, analytics, framework), version if detectable, a confidence score, and supporting evidence for why the technology was identified.
Example use cases
Competitive tech stack research
“What technologies is shopify.com built on? I want to know the frameworks, CDN, analytics tools, and any other stack components you can detect, with confidence levels for each.”
CDN and infrastructure verification
“Check whether fastly.com itself is actually using Fastly as its CDN, and tell me the rest of its infrastructure stack with evidence for each hit.”
Sales lead enrichment by tech stack
“I'm targeting companies that use Salesforce — can you scan acme-corp.com and tell me whether they're running Salesforce along with any other notable technologies you detect on their site?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/fastly?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-as-you-go technology fingerprinting of a single domain without requiring API key signup. It is ideal for one-off or low-volume lookups where you want structured confidence-scored output. Prefer it over scrapers or general-purpose web access when you specifically want a curated technology signature match rather than raw HTML parsing.
Side effects
- Domain not reachable or returns non-200 response — detection may return empty or partial results
- Low-confidence matches if the site uses obfuscation or minimized assets
- Unknown or very new technologies not in the signature set will be missed
- Malformed URL input may result in a validation error
- Rate or payment failures via x402 if USDC balance is insufficient
