Methods

GetAccountNftsAsync(MirrorRestClient, EntityId, params IMirrorQueryParameter[])

Enumerates the NFTs held by the given account. The records are returned newest-first by default (governed by token.id then serialnumber); pass Ascending to reverse.

Declaration

public static IAsyncEnumerable<NftData> GetAccountNftsAsync(this MirrorRestClient client, EntityId account, params IMirrorQueryParameter[] filters)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
EntityId	account	The account whose NFT holdings are requested.
IMirrorQueryParameter[]	filters	Additional query filters. The endpoint supports TokenFilter, SpenderFilter, and SerialNumberFilter, along with the usual PageLimit and OrderBy. The mirror node requires a TokenFilter to be present whenever SerialNumberFilter is used.

Returns

Type	Description
IAsyncEnumerable<NftData>	An async enumerable of NFT records.

GetNftAsync(MirrorRestClient, Nft, params IMirrorQueryParameter[])

Retrieves the record for a specific NFT serial from /api/v1/tokens/{tokenId}/nfts/{serialNumber}.

Declaration

public static Task<NftData?> GetNftAsync(this MirrorRestClient client, Nft nft, params IMirrorQueryParameter[] filters)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
Nft	nft	The identifier of the NFT to retrieve, which includes the token address and the serial number of the NFT.
IMirrorQueryParameter[]	filters	Reserved for forward compatibility. The endpoint currently accepts no query parameters per the OpenAPI spec; any filters supplied here are included in the URL but ignored by the server.

Returns

Type	Description
Task<NftData>	The NFT record, or null if the token/serial pair is unknown to the mirror node.

GetTokenNftsAsync(MirrorRestClient, EntityId, params IMirrorQueryParameter[])

Enumerates the individual NFT serials that have been minted under the given token. The records are returned newest-serial-first by default; pass Ascending to reverse.

Declaration

public static IAsyncEnumerable<NftData> GetTokenNftsAsync(this MirrorRestClient client, EntityId token, params IMirrorQueryParameter[] filters)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
EntityId	token	The NFT class whose individual serials are requested.
IMirrorQueryParameter[]	filters	Additional query filters. The endpoint supports AccountFilter (current holder), SerialNumberFilter, PageLimit, and OrderBy.

Returns

Type	Description
IAsyncEnumerable<NftData>	An async enumerable of NFT records.
