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. web server, CMS, CDN), version if detectable, confidence score, and supporting evidence. The Apache-specific endpoint focuses on Apache server detection but returns the full stack.
Example use cases
Competitor tech stack reconnaissance
“I want to know what technologies my competitor at https://shopify.com is running — server software, CDN, CMS, frameworks, everything. Can you scan it and give me confidence levels for each?”
Apache adoption audit for sales leads
“Check whether https://bigcorp.com is running Apache as their web server — I need to know before reaching out about our migration product. Give me the full stack breakdown too.”
Change detection on a monitored domain
“Re-scan https://targetsite.com for its tech stack. Last time we saw Apache 2.4, WordPress 6.1, and PHP 8.1 on January 15th — let me know if anything has changed.”
Technical details
Endpoint
POSThttps://stack.halowerk.com/stack/articles/apache?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-as-you-go technology stack detection with no signup or API key, especially for ad-hoc or low-volume scans. It is ideal for agents that need to detect Apache specifically, or want incremental change detection by passing previously observed technologies. Prefer over subscription-based alternatives (BuiltWith, Wappalyzer API) when cost-per-call economics favor USDC micropayments.
Side effects
- Domain is unreachable or returns no HTTP response — detection may fail or return empty results
- Domain uses heavy bot protection (Cloudflare, etc.) — fingerprinting signals may be obscured, lowering confidence
- Payment failure via x402 — call rejected before detection occurs
- Invalid URL format — request rejected with validation error
- Rate limiting or blocking by target server — incomplete technology signals
