Quick Start

Synchronous Client

import os
from channel3_sdk import Channel3Client

# Initialize the client
client = Channel3Client(api_key="your_api_key_here")
# Or use environment variable: CHANNEL3_API_KEY

# Search for products
products = client.search(query="blue denim jacket")

for product in products:
    print(f"Product: {product.title}")
    print(f"Brand: {product.brand_name}")
    print(f"Price: {product.price.currency} {product.price.price}")
    print(f"Availability: {product.availability}")
    print("---")

# Get detailed product information
product_detail = client.get_product("prod_123456")
print(f"Detailed info for: {product_detail.title}")
print(f"Brand: {product_detail.brand_name}")
if product_detail.key_features:
    print(f"Key features: {product_detail.key_features}")

# Get all brands
brands = client.get_brands()
for brand in brands:
    print(f"Brand: {brand.name}")
    if brand.description:
        print(f"Description: {brand.description}")

# Get specific brand details
brand = client.get_brand("brand_123")
print(f"Brand: {brand.name}")

Asynchronous Client

import asyncio
from channel3_sdk import AsyncChannel3Client

async def main():
    # Initialize the async client
    client = AsyncChannel3Client(api_key="your_api_key_here")
    
    # Search for products
    products = await client.search(query="running shoes")
    
    for product in products:
        print(f"Product: {product.title}")
        print(f"Score: {product.score}")
        print(f"Price: {product.price.currency} {product.price.price}")
    
    # Get detailed product information
    if products:
        product_detail = await client.get_product(products[0].id)
        print(f"Availability: {product_detail.availability}")
    
    # Get brands
    brands = await client.get_brands()
    print(f"Found {len(brands)} brands")

# Run the async function
asyncio.run(main())

Advanced Usage

Visual Search

# Search by image URL
products = client.search(image_url="https://example.com/image.jpg")

# Search by base64 image
with open("image.jpg", "rb") as f:
    import base64
    base64_image = base64.b64encode(f.read()).decode()
    products = client.search(base64_image=base64_image)

Multimodal Search

# Combine text and image search
products = client.search(
    query="blue denim jacket",
    image_url="https://example.com/jacket.jpg"
)

Search with Filters

from channel3_sdk import SearchFilters, AvailabilityStatus

# Create search filters
filters = SearchFilters(
    brand_ids=["brand_123", "brand_456"],
    gender="male",
    availability=[AvailabilityStatus.IN_STOCK],
    price={"min_price": 50.0, "max_price": 200.0}
)

# Search with filters
products = client.search(
    query="jacket",
    filters=filters,
    limit=10
)

Brand Management

# Get all brands with pagination
brands = client.get_brands(page=1, size=50)

# Search for specific brands
nike_brands = client.get_brands(query="nike")
