How this service works
Does a website use WebP images? Fetches the page (homepage for a bare domain) and matches WebP images's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (images). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no result indicating whether the site uses WebP images, along with the matched evidence snippet (e.g. a fragment of HTML or header that triggered the fingerprint match) and the technology category label 'images'.
Example use cases
Competitor image format audit
“Check whether our main competitor acme.com uses WebP images on their website — I'm trying to understand how modern their image stack is.”
Sales prospecting for WebP migration tools
“I'm selling a WebP conversion service — can you check if bigcommerce.com still hasn't adopted WebP images so I can add them to my outreach list?”
Pre-migration site assessment
“We're about to migrate our client's site and want to know if example.com is already using WebP images before we recommend image optimization changes.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/webp-images?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, single-domain technographic check specifically for WebP image adoption — ideal for sales prospecting, competitor audits, or pre-migration assessments. Prefer this over bulk endpoints when checking a single domain ad hoc, and prefer it over general web scraping when you specifically need WebP detection with structured yes/no output and evidence.
Side effects
- Domain is unreachable or returns non-200 status, resulting in an error or indeterminate result
- Site uses JavaScript-rendered images not present in static HTML, leading to false negatives
- Fingerprint patterns miss obfuscated or unconventional WebP references
- Rate limiting or bot protection on the target site may block the fetch
- Bare domain resolves differently from www subdomain, affecting result accuracy
