TL;DR: Amazon's Buy Box data requires JavaScript rendering—standard HTTP requests won't work. DIY Playwright scrapers fail at scale (35–55% success rate in 2026 conditions). Pangolinfo Scrape API is the production path: >95% success rate, structured JSON output, 5–15 min freshness. Complete working code below.
