How this service works
Trading card portfolio valuation for card-collector and card-investor agents. Returns current market value across Pokemon, MTG, sports cards, and more.
Output
Returns aggregated current market value for the submitted card portfolio, including per-card valuations, total portfolio worth, price trends, and a breakdown by card type or set across Pokemon, MTG, sports cards, and other supported TCG formats.
Example use cases
Assess inherited card collection value
“I just inherited my uncle's trading card collection and I'm not sure what it's worth. He has a bunch of vintage Pokemon cards from the 90s, some old Magic the Gathering cards, and what looks like some baseball cards from the 80s. Can you help me figure out the total value so I know what I'm working with?”
Track portfolio gains for investment
“I've been collecting Pokemon and MTG cards as an investment over the last couple years. I want to see how much my collection has grown in value since I started. Can you give me a current valuation of all my cards together so I can see my total gains?”
Verify collection before selling
“I'm thinking about selling off most of my trading card collection to fund a big purchase. Before I list everything, I need to know exactly what I have and what the current market value is for all of it combined. Can you run a valuation on my entire collection?”
Technical details
Endpoint
GEThttps://gamepulse.theaslangroupllc.com/api/cards/portfolioWhen to prefer
Use this endpoint when an agent needs to value an entire collection of trading cards at once rather than a single card — ideal for card investors wanting portfolio net worth, collectors cataloging holdings, or anyone needing a holistic view across multiple TCG formats (Pokemon, MTG, sports cards). Prefer this over the single-card pricing endpoint when the user has multiple cards and wants an aggregated total.
Side effects
- Unknown or unsupported card name returns partial valuation with missing entries
- Card set or edition not specified leads to averaged or ambiguous pricing
- Unsupported TCG format returns error or empty results
- Stale market data may cause valuation lag during high-volatility periods
- Payment failure (x402) blocks request before valuation is returned
- Malformed card list input returns 400 validation error
