Using an API, if available, simplifies tracking variations, as many APIs return structured data for different product options.

For eBay, monitoring specific sellers’ listings and collecting their item IDs helps track inventory and identify changes over time.

• I store price data with timestamps, enabling analysis of hourly, daily, and weekly trends for various cryptocurrencies.

I set up a loop to cycle through each variation and record details like price or availability, which often differ by variant.

I store metadata alongside product information, as unique identifiers like SKUs are essential for tracking and organizing large datasets.

Binance’s API allows for real-time tracking of prices, which is ideal for high-frequency data collection on volatile assets like crypto.

Storing each variation with a unique identifier, like SKU or ASIN, helps keep data organized and allows me to track specific variants over time.

If using the Amazon API, I retrieve ASINs, SKUs, and other product identifiers in structured format, which is easier than scraping HTML.
