Pass `manual: true` to skip and call `identify()` yourself when ready.\n\n## Signals Collected\n\n- Canvas 2D, WebGL, WebGPU\n- AudioContext timing\n- Font enumeration (650+ fonts)\n- WASM CPU microarchitecture\n- Navigator deep mining\n- CSS media queries\n- Screen & display\n- Prototype lie detection\n- Wallet extension detection (MetaMask, Phantom, etc.) — passive, never triggers popups\n- Storage persistence\n- WebRTC LAN IP\n- And more...\n\nServer-side signals (JA4 TLS, HTTP/2 settings, ASN classification, RTT coherence) are fused automatically at the edge.\n\n## Configuration\n\n```typescript\nconst fiq = new FingerprintIQ({\n apiKey: 'fiq_live_...', // Required\n endpoint: 'https://...', // Custom endpoint (default: fingerprintiq.com)\n timeout: 5000, // API timeout in ms (default: 5000)\n detectWallets: true, // Detect crypto wallets (default: true)\n});\n```\n\nSignal collectors are individually time-boxed so one slow browser API cannot hold up the full `identify()` call. User-Agent Client Hints bootstrap runs in the background and is reused on later calls.\n\n## Response\n\n```typescript\ninterface IdentifyResponse {\n visitorId: string;\n confidence: number; // 0.0 - 1.0\n botProbability: number; // 0.0 - 1.0\n visitCount: number;\n signals: {\n client: { ... };\n server: { ... };\n };\n}\n```\n\n## Sibling Packages\n\n| Package | Purpose |\n|---------|---------|\n| [`@fingerprintiq/js`](https://www.npmjs.com/package/@fingerprintiq/js) | Browser fingerprinting (this package) |\n| [`@fingerprintiq/server`](https://www.npmjs.com/package/@fingerprintiq/server) | Server-side caller classification (Hono, Express) |\n| [`@fingerprintiq/pulse`](https://www.npmjs.com/package/@fingerprintiq/pulse) | CLI usage analytics and machine fingerprinting |\n| [`fingerprintiq`](https://pypi.org/project/fingerprintiq/) (PyPI) | Python SDK — Identify, Sentinel, Pulse |\n\n## Contributing\n\nThis repo is a **read-only public mirror**.
