Expand description

Offers methods helpful in determining account ownership of NFTs and provides a way to page through NFTs per owner, determine total supply, etc.

Required Methods§

Returns the total supply of non-fungible tokens as a string representing an unsigned 128-bit integer to avoid JSON number limit of 2^53.

Get a list of all tokens

Arguments:

  • from_index: a string representing an unsigned 128-bit integer, representing the starting index of tokens to return
  • limit: the maximum number of tokens to return

Returns an array of Token objects, as described in Core standard

Get number of tokens owned by a given account

Arguments:

  • account_id: a valid NEAR account

Returns the number of non-fungible tokens owned by given account_id as a string representing the value as an unsigned 128-bit integer to avoid JSON number limit of 2^53.

Get list of all tokens owned by a given account

Arguments:

  • account_id: a valid NEAR account
  • from_index: a string representing an unsigned 128-bit integer, representing the starting index of tokens to return
  • limit: the maximum number of tokens to return

Returns a paginated list of all tokens owned by this account
