How this service works
Does a website use reCAPTCHA? Fetches the page (homepage for a bare domain) and matches reCAPTCHA's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (security). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no answer indicating whether reCAPTCHA was detected, along with the evidence snippet from the HTML or response headers that triggered the match, and a technology category label (security).
Example use cases
Competitor security stack research
“I'm building a competitor analysis report — can you check if stripe.com uses reCAPTCHA so I can document their bot-protection setup?”
Sales lead technographic enrichment
“Before I reach out to this prospect at acme.com, can you tell me if their site uses reCAPTCHA? I want to pitch our CAPTCHA-alternative solution only to reCAPTCHA users.”
Pre-migration security audit
“We're migrating our client's site away from their current platform — can you scan example-client.com to confirm whether they currently use reCAPTCHA so we know what security tools to replicate?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/recaptcha?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.01) single-technology check specifically for reCAPTCHA presence on a website. It is ideal for sales prospecting workflows, competitor technographic profiling, or pre-migration audits where you need a binary yes/no with supporting evidence rather than a full tech-stack scan. Prefer sibling endpoints for other specific technologies (e.g. WordPress, Shopify, Matomo).
Side effects
- Website is unreachable or returns a non-200 status, resulting in an error or inconclusive result
- Site uses JavaScript-rendered reCAPTCHA that is not present in raw HTML, potentially causing false negatives
- Domain redirects to a page that obscures reCAPTCHA fingerprints
- Rate limiting or bot-blocking by the target site prevents fetching
- Invalid or malformed domain input causes request failure
