Frequently asked questions

browser mode uses Puppeteer (headless Chrome) for full browser rendering with JavaScript execution (5 to 22 seconds, maximum accuracy). It detects JS globals, DOM elements, XHR hosts, CSS rules, and inline scripts. fetch mode makes HTTP-only requests (1 to 3 seconds, best for static sites like WordPress). Both modes cost 5 credits.
Use live detection when GET /v1/domain/{domain} returns a 404 (domain not in the pre-crawled database) or when you need real-time results for a specific URL. The database lookup is faster and cheaper at 1 credit, so always try it first and fall back to live detection only when needed.
interact simulates user behavior in browser mode. Set it to "basic" to scroll the page and trigger lazy-loaded content, or "full" to also accept cookie consent banners (OneTrust, Cookiebot, Didomi, etc.) and fire DOM events. Many European sites block analytics scripts behind cookie consent, so "full" mode reveals technologies that wouldn’t otherwise load. It adds roughly 5 to 10 seconds per request.
Yes. You can use GET /v1/technology-lookup-live?url=https://example.com as a convenience alternative. Pass mode and interact as query parameters. The POST method is recommended when you need to send structured options.
