How this service works
Does a website use CodePen? Fetches the page (homepage for a bare domain) and matches CodePen's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (embeds). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating CodePen detection, an evidence snippet from the HTML or response headers that triggered the match, and the technology category (embeds). If CodePen is not detected, returns a negative result with no evidence.
Example use cases
Competitor tech stack research
“I'm doing competitive research — can you check whether intercom.com uses CodePen on their website? I want to see the evidence snippet too.”
Sales prospect technographic enrichment
“I have a prospect at hubspot.com and I want to know if they're using CodePen — check their homepage and tell me yes or no with any fingerprint evidence you find.”
Migration planning audit
“We're planning to migrate our client's site away from CodePen embeds — can you confirm whether their domain, acmecorp.com, is actually using CodePen right now?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/codepen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) single-technology check specifically for CodePen on a target domain. It is ideal for sales prospecting enrichment, competitor technology research, or migration audits where you only need to confirm CodePen presence. If you need to check multiple technologies at once or want full stack analysis, consider combining with sibling endpoints. For bulk domain checks, prefer a bulk variant if available.
Side effects
- Domain is unreachable or returns a non-200 status, resulting in an error or inconclusive result
- Site uses heavy JavaScript rendering that prevents static fingerprint matching, leading to false negatives
- CodePen usage is only on inner pages, not the homepage, causing false negatives for bare domains
- Rate limiting or bot-blocking by the target site may prevent page fetch
- Invalid or malformed domain input causes a request error
