How this service works
Does a website use Native lazy loading? Fetches the page (homepage for a bare domain) and matches Native lazy loading's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (performance). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating whether the site uses native lazy loading, along with the matched evidence snippet from the HTML or response headers that triggered the fingerprint match, and the technology category ('performance').
Example use cases
Competitor performance stack research
“Check whether our main competitor, bigcommerce.com, uses native lazy loading — I'm doing a performance benchmarking analysis and need to know if they've adopted it.”
Pre-migration technology audit
“Before we migrate our client's site to a new CMS, can you check if their current site at acme.com uses native lazy loading so we know what features to replicate?”
Sales lead technographic enrichment
“I have a prospect at techcrunch.com — can you tell me whether their site uses native lazy loading? I want to pitch them our performance optimization service and need to know their current stack first.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/lazy-loading?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for native lazy loading specifically. Prefer this over a bulk endpoint when checking just one domain, and over a full page audit tool when you only need technographic signal (yes/no + evidence) rather than a comprehensive performance report. Ideal for enriching CRM leads, validating competitor stacks, or automating pre-migration audits one domain at a time.
Side effects
- Domain does not resolve or site is unreachable — returns error with no result
- Site blocks automated crawling (robots.txt, bot detection, 403/429 responses) — may return no evidence
- Homepage redirects or requires authentication — fingerprinting may be incomplete
- Dynamic/SPA sites that inject lazy loading via JavaScript after page load may be missed by HTML-only scanning
- Ambiguous or partial fingerprint matches may produce false negatives
