How this service works
Purpose-bound Cloudflare observation (cdn) using the existing fresh Stack-Monitor. Returns stack_cloudflare_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 structured list of detected technologies for the given URL. Each entry includes the technology name, its category (e.g. CDN, CMS, JavaScript Framework), detected version (or null if unknown), a confidence score, and the evidence or signals that triggered the detection. The response enables complete stack profiling of any public-facing domain.
Example use cases
Competitive tech stack research
“I'm doing competitive research on shopify.com — can you detect their full technology stack and tell me what frontend framework, CDN, analytics tools, and payment infrastructure they're using, with confidence for each?”
Sales prospecting enrichment
“I'm prospecting a lead at notion.so — scan their domain and tell me what CMS, JavaScript frameworks, and marketing tools they have installed so I can personalize my outreach.”
Security audit pre-screening
“Before I run a pentest engagement, scan target-corp.com and list all detected technologies, versions, and categories so I know what attack surface to focus on.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/cloudflare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, confidence-weighted technology fingerprinting of a specific domain without managing API keys or subscriptions — particularly suited for AI agents that need on-demand, pay-per-call stack detection as part of automated enrichment pipelines, competitive research workflows, or sales prospecting. The optional `previous` parameter makes it ideal for change-detection use cases where you want to diff the current stack against a prior observation.
Side effects
- Domain unreachable or non-existent — returns empty results or error
- Heavily obfuscated or minimal sites may yield low-confidence or sparse results
- Rate limits or blocking by the target domain may degrade detection quality
- Invalid URL format in input results in validation error
- Payment failure via x402 protocol prevents the call from executing
