How this service works
Purpose-bound Bunny CDN observation (cdn) using the existing fresh Stack-Monitor. Returns stack_bunnycdn_decision, direct versus inferred status, evidence, optional version difference against a caller-owned baseline and reusable snapshot. Missing fingerprints do not prove absence. No background scheduling, CVE, compatibility or installed-extension inventory. Existing outbound safeguards remain in the injected motor. One public HTTPS root domain, up to150 baseline technologies; 9s timeout.
Output
Returns a list of detected technologies for the given domain, where each entry includes the technology name, category (e.g. CDN, CMS, JavaScript framework), version if detectable, a confidence score, and the evidence signals that triggered the detection.
Example use cases
Competitive tech stack research
“What technologies is shopify.com running right now? I want to know their frontend framework, CDN, analytics tools, and any A/B testing platforms — with confidence levels for each.”
Monitoring stack changes over time
“Last week you told me stripe.com was using Nginx and React. Can you re-scan stripe.com now and compare against those previous findings to see if anything has changed?”
Lead enrichment for sales prospecting
“I'm building a list of prospects who use Salesforce. Can you scan acme-corp.com and tell me whether they have Salesforce or any CRM technology in their stack?”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/bunnycdn?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-call, pay-as-you-go technology detection without committing to a subscription or managing API keys. It is particularly strong when you want structured, confidence-scored output and can optionally supply a prior snapshot to detect stack drift. Prefer it over BuiltWith or Wappalyzer API subscriptions when running sporadic, agent-driven scans or when integrating into an autonomous workflow that pays per use via x402/USDC.
Side effects
- Domain not reachable or returns non-200 status — detection may return empty or partial results
- URL exceeds 2048 characters — request rejected
- Previous snapshot malformed or missing required fields (observed_at, technologies) — validation error
- Rate limiting or bot-detection on target domain may reduce evidence quality
- Unknown or very new technologies may not be identified — gaps in detection coverage
