How this service works
Does a website use ConvertKit? Fetches the page (homepage for a bare domain) and matches ConvertKit's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (email-marketing). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating whether ConvertKit is detected on the site, along with an evidence snippet (the matched HTML or header fragment that triggered the fingerprint) and the technology category label 'email-marketing'.
Example use cases
Competitor email stack research
“I'm doing competitive research — can you check if my top three competitors, hubspot.com, mailchimp.com, and convertkit.com, are using ConvertKit on their own sites?”
Sales lead technographic enrichment
“I have a list of SaaS prospects and I want to know which ones are using ConvertKit so I can pitch them our migration tool — can you start by checking acmecorp.com?”
Pre-migration stack audit
“We're planning to migrate a client from ConvertKit to another platform — can you confirm that their site clientsite.io actually has ConvertKit installed before we start the project?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/convertkit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for ConvertKit specifically. Prefer it over broad technographic APIs when you only need ConvertKit detection and want per-call pricing. Choose the sibling bulk endpoint if you need to check multiple domains at once. Best for sales prospecting workflows, competitive intelligence pipelines, and pre-migration audits where ConvertKit is the technology of interest.
Side effects
- Domain not reachable or returns non-200 status — check may fail or return inconclusive result
- Site uses JavaScript-rendered ConvertKit embeds that aren't visible in static HTML — may return false negative
- Rate limiting or bot protection on target site blocks the fetch — result may be unreliable
- Bare domain redirects to a subdomain or path that differs from the homepage — fingerprint may miss ConvertKit presence
- Payment not processed — call rejected before execution
