Steps
Once connected (see setup above), use the Marketplace Search tool:
- Define the product, filters, and output schema including date, average price, min price, max price, and listing count.
- Run `search_listings` and `watchlist_snapshot` through `marketplace-search` and capture the structured data point.
- Ask Copilot to append each new snapshot to a running dataset, formatted for easy import into a spreadsheet or charting tool.
Example Prompt
Try this with Copilot using the Marketplace Search tool
Use marketplace-search to search for used AirPods Pro 2 across UK marketplaces and save a watchlist snapshot. Return the data as a CSV row with date, average price, min, max, and listing count so I can append it to my tracking spreadsheet.
Tips
- Use the same column schema every run so appending new rows stays seamless.
- Ask Copilot to calculate rolling averages if you have enough data points.
