Usage

Catalog API

The Catalog API provides access to Best Buy's product catalog, categories, store locations, and product recommendations.

from bestbuy.clients.catalog import CatalogClient, AsyncCatalogClient

# Initialize the client
client = CatalogClient(api_key="your-api-key")

Products

# Get a single product by SKU
product = client.products.get(sku=6487435)
print(f"{product.name}: ${product.sale_price}")

# Get specific attributes only
product = client.products.get(sku=6487435, show=["name", "salePrice", "manufacturer"])

# Search for products
results = client.products.search(
    query="manufacturer=apple&salePrice<1000",
    show=["sku", "name", "salePrice"],
    sort="salePrice",
    sort_order="asc",
    page=1,
    page_size=10
)
for product in results.products:
    print(f"{product.sku}: {product.name}")

# List all products
results = client.products.list(page=1, page_size=10)

# Get warranties for a product
warranties = client.products.get_warranties(sku=6487435)

# Paginate through search results
for page in client.products.search_pages(query="onSale=true", page_size=100):
    for product in page.products:
        print(product.name)

# Iterate over individual products across all pages
for product in client.products.search_pages(query="onSale=true").items():
    print(product.name)

# Limit pagination to a maximum number of pages
for product in client.products.search_pages(query="onSale=true", max_pages=5).items():
    print(product.name)

Categories

# Get a single category
category = client.categories.get(category_id="abcat0100000")
print(f"{category.name}: {category.id}")

# Search for categories
results = client.categories.search(query="name=Laptops*")
for category in results.categories:
    print(category.name)

# List all categories
results = client.categories.list(page=1, page_size=10)

# Paginate through categories
for category in client.categories.search_pages().items():
    print(category.name)

Async Catalog Client

import asyncio
from bestbuy.clients.catalog import AsyncCatalogClient

async def main():
    client = AsyncCatalogClient(api_key="your-api-key")

    # All operations are async
    product = await client.products.get(sku=6487435)
    print(product.name)

    # Async pagination
    async for product in client.products.search_pages(query="onSale=true").items():
        print(product.name)

asyncio.run(main())

Commerce API

The Commerce API provides access to Best Buy's order management, fulfillment options, pricing, and payment services.

from bestbuy.clients.commerce import CommerceClient, AsyncCommerceClient

# Initialize the client (sandbox mode by default)
client = CommerceClient(
    api_key="your-api-key",
    username="your-username",  # For registered orders
    password="your-password",
    sandbox=True  # Use sandbox environment
)

# Production mode
client = CommerceClient(
    api_key="your-api-key",
    sandbox=False
)

Authentication

Authentication is required for registered orders (orders charged to your company credit card).

# Using context manager (recommended)
with client.auth:
    # Session is automatically managed
    response = client.orders.submit_registered(order)
# Session is automatically logged out

# With explicit credentials
with client.auth(username="user", password="pass"):
    response = client.orders.submit_registered(order)

# Manual login/logout
client.auth.login()
try:
    response = client.orders.submit_registered(order)
finally:
    client.auth.logout()

Fulfillment Operations

# Check product availability
availability = client.fulfillment.check_availability(sku="5628900")
print(f"Shipping available: {availability.available_for_shipping}")
print(f"Pickup available: {availability.available_for_pickup}")
print(f"Delivery available: {availability.available_for_delivery}")
print(f"Max quantity: {availability.max_quantity}")

# Get shipping options
shipping = client.fulfillment.get_shipping_options(
    sku="5628900",
    address1="123 Main St",
    city="Minneapolis",
    state="MN",
    postalcode="55401"
)
for option in shipping.options:
    print(f"{option.name}: ${option.price} - Delivery by {option.expected_delivery_date}")

# Find stores with product availability
stores = client.fulfillment.find_stores(
    sku="5628900",
    zip_code="55401",
    store_count=5
)
for store in stores.stores:
    print(f"{store.name}: {store.availability_msg}")

# Get home delivery options (for large items)
delivery_options = client.fulfillment.get_delivery_options(
    sku="5628900",
    zip_code="55401"
)
for option in delivery_options.options:
    print(f"{option.delivery_date}: {option.start_time} - {option.end_time}")

# Get delivery services (installation, haul away, etc.)
services = client.fulfillment.get_delivery_services(
    sku="5628900",
    zip_code="55401"
)
for service in services.delivery_services:
    print(f"{service.service_display_name}: ${service.price}")

Pricing Operations

# Get unit price for a SKU
price = client.pricing.get_unit_price(sku="5628900")
print(f"Price: ${price.unit_price.value}")

# Get combined product service info (availability, price, shipping, stores)
product_info = client.pricing.get_product_service(
    sku="5628900",
    zip_code="55401"
)

    Tender,
)

# Create a registered order (requires authentication)
order = OrderSubmitRegisteredRequest(
    id="my-order-123",
    order_list=OrderList(
        id="list-1",
        items=[
            OrderItem(
