What it does for you
Collect prices even when the HTML fights back
Some product pages hide their prices and break standard scrapers. This n8n workflow has Gemini read a screenshot, falls back to text if the reading looks doubtful, then checks every price before writing it to Google Sheets.
- Get a sheet of checked prices, row by row
- Spot mismatches thanks to cross-checking
- Know which method was used for each row
