How this service works
Third-party script and iframe hosts on a page, each classified (analytics, ads, tag manager, chat, session replay, social, consent, CDN), the cookies its first response sets (names and flags only, never values) and whether a known consent manager is present. Static HTML only: scripts added at run time are not seen.
Output
Returns a JSON object with the scanned URL, timestamp, a list of third-party trackers with their categories, all cookies set (including security flags like Secure/HttpOnly/SameSite), the detected consent manager (if any), a total third-party count, and an attribution note. Analysis is static HTML only — JavaScript-rendered trackers are not detected.
Example use cases
Privacy audit for a competitor site
“Check https://www.shopify.com/ for all the trackers and analytics tools it uses — I want to know what third-party scripts and cookies they're setting and whether they have a consent manager.”
Compliance check before launch
“Before we go live, can you scan https://staging.mycompany.com/ and list every third-party tracker and cookie it sets? I need to know if we're running anything that requires GDPR consent.”
Detecting ad trackers on a news site
“Scan https://www.dailymail.co.uk/ and tell me how many third-party advertising trackers and cookies it loads — I want to see the full list of what's tracking me there.”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/trackers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly identify what third-party trackers, analytics tools, cookies, and consent managers a specific webpage embeds at the static HTML level. It is ideal for privacy audits, GDPR/CCPA compliance checks, and competitive intelligence on tracking stacks. Prefer this over a full browser-based audit when speed matters and JavaScript-rendered trackers are not the primary concern.
Side effects
- Invalid or malformed URL returns an error
- Non-HTTPS URLs may be rejected
- JavaScript-injected trackers are not detected (static HTML only)
- Private or localhost URLs will fail
- Rate limiting or payment failure returns 402
- Paywalled or bot-protected pages may return incomplete results
