The Card Arbitrage Lookup endpoint returns a grading profitability analysis for trading cards, including raw market prices, PSA graded prices for grades 9 and 10, net spreads after grading fees, projected ROI percentages, and the best grade to target.
Key fields in the response include "title," "platform," "rawPrice," "gradingFee," "grades" (with details for grade 9 and grade 10), "best" (indicating the optimal grade), and "productUrl" for further details.
The response data is structured as a JSON object containing a success flag, grading fee, count of results, and an array of results. Each result includes detailed information about the card and its grading profitability.
The endpoint provides information on trading card names, raw market prices, PSA graded prices for grades 9 and 10, grading fees, net spreads, projected ROI, and the best grade to target for grading.
The primary parameter for the Card Arbitrage Lookup endpoint is the card name. Users can customize their requests by specifying different card names to receive tailored grading profitability analyses.
Users can analyze the grading profitability by comparing raw prices with graded prices, assessing the spread and ROI for each grade, and identifying the best grade to target for maximizing profits.
The data is sourced from various trading card marketplaces and sales platforms, ensuring a comprehensive view of market prices and grading trends for trading cards.
Typical use cases include identifying profitable cards to grade for resale, comparing potential returns on investment, and assisting collectors and flippers in making informed grading decisions.
