Build a Multi‑Site Competitor Price Monitor in 10 Minutes (No Selectors, No Selenium)

Описание и применение

Создайте мониторинг цен конкурентов на нескольких сайтах за 10 минут без селекторов и Selenium, используя API Scraping AI, Slack‑уведомления и бесплатный GitHub Actions.

Задача

Custom scrapers for each e‑commerce site are fragile, requiring constant selector maintenance and complex parsing for price formats.

Результат

• 2. Create SQLite DB for price history
• 3. Define monitor_url function that calls Scraping AI with a schema
• 4. Compare current price to last stored price
• 5. If price dropped, format alert and POST to Slack webhook
• 6. Log new price to database
• 7. Schedule script on GitHub Actions cron

Доказательства
