Tutorials, industry analysis, and best practices for ecommerce data extraction, API integration, and competitive intelligence.
Turn an Amazon seller ID such as A2I59UVTUWUFH0 into a name, feedback numbers and storefront links: where seller IDs appear in API responses, which IDs belong to Amazon itself, and a cached lookup that pays for each ID once.
Get an alert when a competitor's Amazon listing runs out of offers, loses its featured offer or Amazon itself stops selling it: one offers call per check, a state per listing, and a second check before alerting so a single empty page never triggers a false alarm.
Judge how hard an Amazon keyword is from the first results page: sponsored share, price band, the review barrier of the top 10 organic results and the words competitors use in titles - one credit per keyword, in Python.
Estimate how much an Amazon category sells per month: take its top 50 bestsellers, estimate each product's monthly units, multiply by price, then measure how concentrated the revenue is with the top-3 share and the HHI - about 51 credits per category, in Python.
Find products that reached an Amazon bestseller list within weeks of launch: read the top 50 of a category, look up each ASIN's Date First Available once, cache it, and filter by age - about 51 credits for the first run and a handful per week after.
Monitor Amazon listings for changes with one lookup per ASIN: snapshot title, bullets, images, variations and A+ content, ignore cosmetic noise such as image size variants, and report real content changes apart from price moves.
Get Amazon product data in Ruby with nothing but the standard library: a Net::HTTP client for product lookup and keyword search, a retry policy that never pays twice for the same miss, a thread pool for bulk lookups, and how to call it from Rails.
Get an ASIN's Buy Box holder history with one API call, turn it into each seller's share of time, spot when Amazon itself takes or leaves the Buy Box, and read the privateLabel and shareBuyBox flags correctly.
Fetch Amazon product details, keyword search results and prices from Node.js with nothing but the built-in fetch: a dependency-free client, the three price formats the API returns, and a bounded worker pool for parallel requests.
