Who this is for
This n8n-powered automation uses Bright Data's MCP Client to extract real-time data from a price drop site listing the amazon products, including price changes and related product details.

The Amazon Price Drop Intelligence Engine is designed for:
-
Ecommerce Analysts who need timely updates on competitor pricing trends
-
Brand Managers seeking to understand consumer sentiment around pricing
-
Data Scientists building pricing models or enrichment pipelines
-
Affiliate Marketers looking to optimize campaigns based on dynamic pricing
-

What problem is this workflow solving?
This workflow solves several key pain points:
Reliable Scraping: Uses Bright Data MCP, a managed crawling platform that handles proxies, captchas, and site structure changes automatically.
Insight Generation: Transforms unstructured HTML into structured data and then into human-readable summaries using Google Gemini LLM.
Sentiment Context: Goes beyond raw pricing data to reveal how customers feel about the price change, helping businesses and researchers measure consumer reaction.
Automated Reporting: Aggregates and stores data for easy access and downstream automation (e.g., dashboards, notifications, pricing models).
