Realistic device fingerprints, on demand.
Internally-consistent browser profiles at scale. One API call returns a complete, plausible machine with matching GPU, CPU, screen, fonts, locale and voices.
One GET returns a whole machine
Authenticate with your API key as the key query parameter and pass filters per request. /generate synthesizes a fresh profile; /random returns a real collected one.
import requests
r = requests.get("https://api.capzy.ai/fingerprint/generate", params={
"key": "YOUR_API_KEY",
"format": "chromium", # or "raw"
"tags": "Windows", # Windows | macOS | Linux
"country": "us",
})
fp = r.json()
print(fp["userAgent"]["userAgent"])1. Request
One authenticated GET with your filters (format, platform, country, version). No SDK, no pooling to manage.
2. Synthesize
We assemble one internally-consistent machine: matching GPU, CPU, screen, fonts, locale, timezone and voices.
3. Inject
Drop the chromium payload into Playwright / Patchright / Puppeteer / Selenium, or take the raw primitives.
Coherent, fresh, injection-ready
Coherent by design
Every profile is one plausible machine: GPU, CPU, OS and browser from compatible eras and tiers. No flagship GPU on a decade-old CPU.
Two formats
chromium (ready to inject) or raw (UA, canvas, fonts, visitor_id). Filter by platform, country and browser version.
Always fresh
Browser builds, GPUs and OS versions are tracked continuously, weighted to what's actually in use.
Injection-ready output
The chromium format drops straight into Playwright, Patchright, Puppeteer or Selenium. The raw format gives you the primitives.
