- Wire the data into your collection management or appraisal application
Example Prompt
Try this with Copilot using the Trading Cards tool
Use trading-cards to look up the top cards and current values for Wayne Gretzky and Mario Lemieux. Return typed JSON with player, card_name, set, year, grade, rarity, recent_sale_price, currency, and estimated_value for use in a collection valuation tool.
Tips
- Structure the output with a collection_id field so individual cards can be linked back to a specific collection record
- Include estimated_value and recent_sale_price as separate numeric fields for portfolio calculation logic
- Add a grade_worthwhile boolean field that your app can compute based on value differential between raw and graded
