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 for the given domain, each with a name, category (e.g. CMS, CDN, JavaScript framework), version if detectable, a confidence score, and supporting evidence for the detection hit.
Example use cases
Competitive tech stack research
“What technologies is competitor.com using — I want to know their CMS, frontend framework, CDN, and any marketing tools, with confidence scores for each one?”
Monitoring stack changes over time
“Check what technologies are running on mybrand.io now — last time we observed it on 2024-11-01 it was using WordPress 6.3, React, and Cloudflare. Has anything changed?”
Lead enrichment for SaaS sales
“I need to know what technology stack prospect-startup.com is running so I can tailor my sales pitch — specifically whether they're using any competing tools or platforms we integrate with.”

Endpoint
POSThttps://stack.halowerk.com/stack/articles/elementor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need accurate, evidence-backed technology detection for any public domain without requiring signup or API keys. It is especially suitable for AI agents that need to enrich lead data, perform competitive research, or monitor technology changes, and where a low per-call micropayment model (via x402 USDC) is preferable to a subscription. The optional `previous` snapshot parameter makes it ideal for change-detection workflows.
Side effects
- Invalid or unreachable URL returns an error or empty technology list
- Domain blocks fingerprinting techniques, leading to incomplete or low-confidence results
- Payment failure via x402 returns HTTP 402 and no results are returned
- Malformed input schema (missing required fields) returns a validation error
- Rate limits or upstream scanning issues may cause timeouts
