nft_getAsset – Mythos Gaming RPC

nft_getAsset returns enriched metadata for Mythos NFTs by combining pallet_nfts storage and collection configuration. Use it to show live ownership inside your game client without decoding SCALE manually; under the hood it reads pallet_nfts::Item, metadata, and price records in a single pass.

Parameters

Parameter	Type	Required	Description
collectionId	string	Yes	Hex or decimal identifier of the collection
itemId	string	Yes	Hex or decimal identifier of the item
at	string	No	Optional block hash for historical queries

Response Fields

Field	Type	Description
collectionId	string	Echo of the requested collection
itemId	string	Echo of the requested item
owner	string	Account ID holding the asset
locked	boolean	Indicates transfer or attribute locks
metadata	object	UTF-8 metadata and attributes (namespaces flattened)
price	object	Active listing data from pallet_marketplace, if present

Request Example

{
  "jsonrpc": "2.0",

    { "collectionId": "0xfa", "itemId": "0x02" }
  ],

Response Example

{
  "jsonrpc": "2.0",
  "result": {
    "collectionId": "0xfa",
    "itemId": "0x02",
    "owner": "0x6f889bd1f2f17cf62f6be41996d0d33df7f8fa7a7f6a0c7003c965c4c068b0d5",

      "season": "S4",
      "rarity": "Legendary"
    },
    "price": null
  },
  "id": 7
}

The owner and item identifiers match the on-chain nfts.mint extrinsic at block 2,611,955.

Error Handling

Code	Meaning	Resolution
AssetNotFound	Collection or item missing	Confirm the IDs and ensure the collection exists (check NextCollectionId).
InvalidParameter	Malformed IDs	Use decimal strings ("250") or hex prefixed with 0x

Integration Tips

• Cache responses client-side; metadata rarely changes unless admins update attributes.
• Pair with gaming_getPlayerAssets to hydrate inventories on login.
• Surface DAO badge metadata to highlight governance participation in-game.
