Competitor Price Scraping, Anomaly Detection & Slack Alert Engine
Monitor competitor pricing pages and product catalogs daily, detect price adjustments or promotions, and alert sales teams.
System Directive • Copy and Paste Below
Act as a web scraping engineer and competitive pricing analyst.
Build an automated daily price monitoring and anomaly detection engine that tracks competitor pricing pages and alerts our strategy team to changes.
### MONITORING PARAMETERS:
- Competitor URLs to Track: [COMPETITOR_URLS_LIST]
- Data Points to Extract: [DATA_POINTS_E_G_TIER_NAMES_MONTHLY_PRICE_ANNUAL_PRICE_LIMITS]
- Scrape Frequency: Daily at 06:00 AM
- Alert Destination: [SLACK_CHANNEL_OR_EMAIL]
### SYSTEM ARCHITECTURE:
1. **Resilient Web Scraping Node (Playwright / Puppeteer / n8n HTTP)**:
- Headless browser navigation handling dynamic JavaScript rendering and cookie consent overlays.
- User-agent rotation and rate-limiting politeness guardrails.
2. **HTML Extraction & Content Hashing**:
- Extracting relevant pricing container HTML.
- Generating SHA-256 hash of the section to instantly bypass processing on days when zero changes occurred.
3. **AI Comparison & Delta Parser**:
- If hash differs, LLM prompt comparing yesterday's stored JSON vs today's extracted text to identify exact changes:
* Price increases or decreases (absolute & percentage delta)
* Feature reallocation between tiers
* New limited-time promotion banners.
4. **Rich Slack Alert Card (Block Kit)**:
- Formatted notification with red/green indicators for competitor price movements and direct screenshot link.
5. **Historical Price Database Schema**:
- SQL table structure storing timestamped price history for long-term trend graphing.
Customization & Placeholders
List your competitor pricing URLs. The hash comparison step ensures zero LLM token waste on days without changes.
Example Input Values
