Fingerprint Pro billing is based on API usage (device identifications), so it is important to make the most of your subscription’s monthly API limit. We recommend calling the API only when the
visitorId will be processed or saved by your application.
We offer framework-specific libraries for React, Next, Vue, Svelte, Preact, and Angular with a built-in
visitorIdcaching mechanism. Use one of our frontend libraries to cache visitor identifiers and reduce the number of API requests.

Device fingerprinting for native mobile apps
For mobile device identification, we highly recommend using our native SDKs for Android and iOS. For device identification that is scoped to the browser instance, a unique ID called
visitorIdis generated per browser. If a visitor switches to a different browser on the same device, a new
visitorIdis generated for that browser.
