How to Detect LinkedIn Ads on Any Website (API Guide)
A company running LinkedIn Ads has a B2B acquisition budget and someone accountable for pipeline, and the proof is sitting in its own HTML. How the LinkedIn Insight Tag is fingerprinted from _linkedin_partner_id, snap.licdn.com, and the px.ads.linkedin.com pixel, how to spot it manually in DevTools, why Google Tag Manager hides it from view-source, and how to automate detection across a whole prospect list. Includes a live worked example, curl examples for /demo, /analyze, /check, and /analyze/batch, and the canonical-name gotcha that breaks naive jq filters.

Find Companies Using imagesLoaded: API Guide (2026)
imagesLoaded is a narrow JavaScript library with a broad implication: a site loading it has an image-heavy layout still computed in jQuery-era JavaScript, usually enqueued by a WordPress theme or page builder that names itself in the same scan. How the imagesloaded.min.js script signature is detected, why the ?ver= query string hands you the library version for free, and why bundled copies are invisible to every external scanner. Includes a live worked example against a real WordPress site, curl examples for /demo, /check, /lookup, and /analyze/batch, and a copy-pasteable Python pipeline that exports a CRM-ready CSV of modernization prospects.

How to Detect Typekit (Adobe Fonts) on Any Website (2026)
Typekit was rebranded to Adobe Fonts in 2018, but the serving infrastructure kept the old hostnames, and those hostnames are the detection signature. Three manual checks that settle the question in under a minute: the use.typekit.net stylesheet and use.typekit.com script embeds in the page source, the kit ID and wf-loading body classes, and network requests to p.typekit.net. Then the programmatic version: real curl examples against /demo, /analyze, and /analyze/batch, why the API returns both Typekit and Adobe Fonts for one integration, why a non-200 status code means inconclusive rather than absent, and a comparison table for telling Typekit, Google Fonts, and self-hosted fonts apart.

How to Find Companies Using Adobe Fonts (API Guide 2026)
Adobe Fonts is one of the few front-end signals that maps to a budget rather than a technology preference: it rides on a paid Creative Cloud subscription, so every site serving fonts from use.typekit.net pays Adobe for typography. How the use.typekit.net stylesheet and use.typekit.com script embeds are detected, why scans return both Adobe Fonts and Typekit for the same integration, and why the signal leaves no DNS trace. Includes real curl examples for /demo, /analyze, /check, and /analyze/batch against a live site, a copy-pasteable Python pipeline that exports a CRM-ready CSV, and an Adobe Fonts vs Google Fonts comparison for reading design budgets from the outside.

How Klaviyo is detected from the klaviyo.js script source, why the _learnq global is visible in a browser but not to a server-side scanner, and what Klaviyo Forms, Klaviyo Reviews, and Klaviyo Customer Hub each tell you about how deeply a merchant has committed. Includes real curl examples for /demo, /analyze, /check, /analyze/batch, and /lookup, a copy-pasteable Python pipeline that exports a CRM-ready CSV, and the status_code caveat that silently drops real Klaviyo users from most prospect lists.
