3. Technical Methods for Acquiring Invincible Data

There are two primary methods for acquiring data: using standardized API interfaces and employing web scraping techniques to extract webpage content. Below, we introduce the advantages, disadvantages, and use cases of each method.

3.1 API Method

3.1.1 Advantages of Using APIs

• Standardized format: Data is structured and consistent.

• High reliability: Data is accurate and updates in real-time.

• Ease of development: APIs require simple HTTP requests, eliminating the need to parse complex HTML structures, reducing maintenance costs.

3.1.2 Practical Example: Fetching Data via Python API

The following example demonstrates how to retrieve Invincible product data using a third-party API (e.g., LuckData Sneaker API).

import requests
# Replace with your API Key
API_KEY = 'your_luckdata_key'
headers = {
'X-Luckdata-Api-Key': API_KEY
}
# Target product page URL (adjust accordingly)
url = 'https://www.invincible.com.tw/Product.aspx?yano=20241203000001&co=115'
# API request URL
api_url = f'https://luckdata.io/api/sneaker-API/get_17un?url={url}'
response = requests.get(api_url, headers=headers)
if response.status_code == 200:
data = response.json()
print("API Response:", data)
else:
print(f"Request failed, status code: {response.status_code}")

With this approach, you can obtain structured data, including product names, prices, stock availability, image links, and release dates.

3.2 Traditional Web Scraping

3.2.1 Static Page Scraping

For web pages that do not rely on JavaScript for content rendering, you can use Python’s requests and BeautifulSoup libraries to fetch and parse HTML data:

import requests
from bs4 import BeautifulSoup
# Target product listing page
url = 'https://www.invincible.com.tw/ProductList.aspx?i1=02&i2=01'
headers = {'User-Agent': 'Mozilla/5.0'}
response = requests.get(url, headers=headers)
if response.status_code == 200:
soup = BeautifulSoup(response.content, 'html.parser')
# Locate product names based on the website's structure
products = soup.find_all('div', class_='product_name')
for product in products:
print(product.get_text(strip=True))
else:
print(f"Request failed, status code: {response.status_code}")

3.2.2 Dynamic Content Scraping

For pages that load content dynamically via JavaScript, Selenium can be used to simulate browser interaction and retrieve fully rendered content:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
# Set ChromeDriver path
service = Service('path_to_chromedriver')
options = webdriver.ChromeOptions()
options.add_argument('--headless')
driver = webdriver.Chrome(service=service, options=options)
driver.get('https://www.invincible.com.tw/ProductList.aspx?i1=02&i2=01')
try:
products = WebDriverWait(driver, 10).until(
EC.presence_of_all_elements_located((By.CLASS_NAME, 'product_name'))
)
for product in products:
print(product.text)
finally:
driver.quit()

3.2.3 Comparison of Methods

• API Approach: Structured data, high reliability, but limited by subscription plans and request quotas.

• Web Scraping: More flexible and customizable but requires handling anti-scraping mechanisms and changing webpage structures, leading to higher maintenance costs.

3.3 Proxy Technology in Web Scraping

When scraping data from Invincible, issues like IP blocking and anti-scraping mechanisms may arise. Proxy IP services help mitigate these risks by distributing requests across multiple IP addresses, reducing the likelihood of being blocked.

For instance, LuckData provides proxy services, including data center proxies, dynamic residential proxies, and unlimited rotating proxies. These services offer global coverage, fast IP rotation, and precise geolocation capabilities, ensuring stable web scraping operations.

Here’s a simple Python example using proxies:

import requests
# Replace with your proxy account details
proxy_ip = "http://Account:Password@ahk.luckdata.io:Port"
url = "https://api.ip.cc"
proxies = {
'http': proxy_ip,
'https': proxy_ip,
}
data = requests.get(url=url, proxies=proxies)
print("Proxy Response:", data.text)

Using proxy technology helps prevent IP bans caused by excessive requests from a single IP, ensuring continuous and stable data collection.

4. Data Applications and Business Insights

4.1 Use Cases

Once Invincible data is collected, it can be applied to various scenarios, including:

• Price Monitoring & Comparison: Track real-time price fluctuations to help consumers make informed purchase decisions.

• Stock Forecasting: Predict demand for popular products to adjust stock and marketing strategies.

• Promotion Effectiveness Analysis: Assess sales changes before and after promotions.

• Competitive Analysis: Gather competitor data to refine e-commerce strategies.

4.2 Data-Driven Decision Making

Businesses and developers can store, integrate, and analyze the collected data to drive strategic decisions:

• Time-series analysis for inventory forecasting.

• Machine learning models to analyze price sensitivity.

• Big data integration for deep market trend insights and precision marketing.

5. Future Trends and Technological Outlook

As data technology and artificial intelligence evolve, API and web scraping techniques will continue to integrate, supported by proxy IP services and cloud computing for more efficient data acquisition. Additionally, cross-platform data integration and smart analysis will become essential for e-commerce and market research, helping businesses gain a competitive edge.
