How this service works
Match a natural language card description to the best card in the CardHedge database.
Output
Returns the best-matching card record from the CardHedge database, including the card ID, name, set, and associated metadata. The card ID can then be used to fetch pricing, comparable sales, or graded values via other CardHedge endpoints.
Example use cases
Identify card before pricing lookup
“I have a card described as '2003 Topps LeBron James rookie base' — can you match it to the right card in CardHedge so I can look up its current price?”
Pokémon card disambiguation
“I'm trying to figure out which exact card 'Charizard Base Set 1st Edition holo' maps to in the CardHedge database — can you match it under the Pokémon category with 10 candidates for best accuracy?”
Bulk listing card resolution
“I'm listing cards for sale and need to resolve '2017 Panini Prizm Patrick Mahomes rookie' to the correct CardHedge card entry — can you match it and give me the card details?”
Technical details
Endpoint
POSThttps://api.cardhedger.com/v1/agent/cards/card-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a human-readable card description and need to resolve it to a structured CardHedge card record or card ID. It is the recommended first step before calling any other CardHedge endpoint that requires a card_id. Prefer this over the general search endpoint when the goal is to identify the single best matching card rather than browse a filtered list.
Side effects
- No match found if the description is too vague or misspelled
- Low-confidence match if multiple similar cards exist in the database
- Timeout or slower response when max_candidates is set to 10
- Category filter mismatch if the wrong category is specified, excluding the correct card
- Query too short (under 3 characters) returns a validation error
