Package Exports
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (arbitrage-api-cryptoscan) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation
# Install dependencies
npm install
# Start the service
bun startConfiguration
The service supports configuration via environment variables:
# Required environment variables
PORT=3000 # Server port (default: 3000)
MIN_SPREAD=1 # Minimum spread percentage
MAX_SPREAD=999 # Maximum spread percentageWebSocket API
Connecting
const ws = new WebSocket('ws://localhost:3000');Message Format
Received messages follow this structure:
interface ArbitrageMessage {
exchangeFrom: string; // Source exchange
exchangeTo: string; // Target exchange
symbol: string; // Trading pair (e.g., "BTCUSDT")
network: string; // Transfer network ID
spread: number; // Profit percentage
buyPrice: number; // Entry price
sellPrice: number; // Exit price
