Overview

EU-Utility V3 provides a unified API for plugin development. Plugins run in a secure sandbox with controlled access to system resources.

API Structure

// Access the API
const api = window.EUPluginAPI;

// All methods return Promises
const result = await api.someMethod();

PluginAPI

Log Reader

// Read last N log lines
const lines = await api.readLogLines(100);

// Read since timestamp
const recent = await api.readLogSince(Date.now() - 300000);

// Read filtered
const loot = await api.readLogFiltered('Loot:');

Returns: Promise<string[]>

Window Manager

// Get game window info
const window = await api.getGameWindow();

// Check focus
const focused = await api.isGameFocused();

// Bring to front
await api.bringGameToFront();

// Capture screenshot
const screenshot = await api.captureGameWindow();

WindowInfo:

interface WindowInfo {
  x: number;
  y: number;
  width: number;
  height: number;
  isFocused: boolean;
}

OCR Service

// Check availability
const available = await api.ocrAvailable();

// Recognize text
const text = await api.recognizeText({
  x: 100,
  y: 100,
  width: 200,
  height: 50
});

Returns: Promise<string>

Item Database API

// Search items
const results = await api.searchItems({
  query: 'weapon',
  category: 'equipment',
  limit: 10
});

// Get item details
const details = await api.getItemDetails('12345');

SearchResult:

interface Item {
  id: string;
  name: string;
  type: string;
  category: string;
  value?: number;
  markup?: number;
}

HTTP Client

// GET request
const data = await api.httpGet('https://api.example.com/data', {
  cache: true,
  ttl: 3600
});

// POST request
const result = await api.httpPost('https://api.example.com/save', {
  key: 'value'
});

Notifications

await api.showNotification({
  title: 'Alert',
  body: 'Something happened',
  duration: 3000
});

Clipboard

// Copy
await api.copyToClipboard('text');

// Paste
const text = await api.pasteFromClipboard();

Event Bus

// Subscribe
const subId = await api.subscribeEvent('loot.received', (event) => {
  console.log(event.data);
});

// Unsubscribe
await api.unsubscribeEvent(subId);

// Publish
await api.publishEvent('my.event', { data: 'value' });

Data Storage

// Save
await api.savePluginData('myPlugin', 'key', { data: 'value' });

// Load
const data = await api.loadPluginData('myPlugin', 'key');

// Delete
await api.deletePluginData('myPlugin', 'key');

WidgetAPI

Creating Widgets

// Create overlay widget
const widget = await api.createWidget({
  id: 'my-widget',
  title: 'My Widget',
  width: 300,
  height: 200,
  x: 100,
  y: 100
});

// Update content
await api.updateWidget('my-widget', {
  title: 'Updated',
  content: htmlContent
});

// Close widget
await api.closeWidget('my-widget');

ExternalAPI

REST Endpoints

The application exposes a local REST API for external integrations.

GET  /api/plugins           - List all plugins
POST /api/plugins/{id}/activate
POST /api/plugins/{id}/deactivate
GET  /api/loot/recent       - Recent loot events
POST /api/ocr/recognize     - OCR text recognition

TypeScript Types

// Full type definitions for plugin development
