The device intelligence API that detects eSIM compatibility, identifies fraud signals, and routes every user to the right flow — automatically, in milliseconds.
No build step required. Drop in one script tag and start detecting device signals instantly.
Drop a single <script> tag into your page. No build step, no npm install required. Works with any stack.
SignalLayer silently collects device signals and matches against our database to identify the exact model, eSIM capability, and fraud indicators in real time.
Use device signals and risk scores to show eSIM-compatible shoppers the right install flow, block fraud, and redirect incompatible devices gracefully.
Built for eSIM providers who need accuracy, speed, and fraud protection at scale.
Combines UA parsing, screen resolution, DPR, OS signals, and GPU fingerprinting for 90%+ accuracy across all major device families.
Coverage for 10,000+ device models — iPhone, Samsung Galaxy, Google Pixel, and more — continuously updated as new devices launch.
Automatically determine the best install flow for each device — QR code, push install, or guided setup — and route users without any manual logic.
Track device events, eSIM adoption rates, geographic distribution, and conversion strategies in your dashboard — updated in real time.
The entire SDK is vanilla JavaScript. No React, no Vue, no bundle bloat. Under 15 KB gzipped — your pages stay fast.
Detect VPN/proxy usage, emulator traffic, and suspicious IPs using Cloudflare edge intelligence and proxycheck.io — before a fraudulent purchase completes.
Integrate in minutes, not hours. SignalLayer handles everything from signal collection to risk scoring — you just act on the result.
Every signal is designed to move shoppers through your funnel more efficiently — and keep bad actors out.
Route eSIM-capable shoppers directly to the right activation flow. Fewer steps, less friction, higher conversion — without any manual effort.
Stop customers from buying eSIM plans their devices can't use. Show compatibility status before checkout and eliminate frustrated refund requests.
Fewer incompatible purchases means fewer support tickets, fewer chargebacks, and less time your team spends resolving preventable issues.
Detect VPN traffic, emulators, and high-risk IPs before checkout completes. Block bad actors without adding friction for legitimate users.
Every device check returns a structured set of signals — from hardware specs to security signals — ready to act on.
Optimize user journeys, prevent incompatible purchases, and increase conversions — all with simple usage-based pricing.
