The ERC721 Media API provides a standardized approach for allowing third party access to media files for ERC721 NFTs if the owner gives permission.
Example of media files are:
- Rigged 3D models in VRM, FBX and GLB formats to be used in open worlds such as Cryptovoxels, Sandbox, Decentraland or Somnium
- 2D sprite sheets to use in 2D based worlds such as worldwideweb3
