🏃‍♂️ Quick Start

Basic Usage

import { Channel3Client } from 'channel3-sdk';

const client = new Channel3Client({
  apiKey: process.env.CHANNEL3_API_KEY!,
});

// Search for products
const products = await client.search({
  query: 'blue denim jacket',
});

console.log(`Found ${products.length} products`);
products.forEach((product) => {
  console.log(`${product.title} - $${product.price.price} ${product.price.currency}`);
});

Advanced Search with Configuration

// Search with custom configuration and context
const results = await client.search({
  query: 'running shoes',
  config: {
    enrich_query: true, // Enable query enrichment
    semantic_search: true, // Enable semantic search
  },
  context: 'Looking for athletic footwear for marathon training',
  filters: {
    price: { min_price: 50, max_price: 200 },
    gender: 'male',
    brand_ids: ['nike-id', 'adidas-id'],
  },
  limit: 10,
});

Visual Search

// Search by image URL
const imageResults = await client.search({
  image_url: 'https://example.com/product-image.jpg',
});

// Search by base64 image
const base64Results = await client.search({
  base64_image: 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQ...',
