Response fields of One NFT's transfers or sales
Field	Type	Description
`contract`	string	The collection contract, lowercase.
`tokenId`	string	The token id, in decimal.
`type`	string	The history asked for.
`transfers`	object[] \| null	Newest first. `null` when `type` is `sales`. An empty list means no transfer is known — a token id the collection never minted answers the same.
`transfers[].at`	string \| null	Block time, ISO-8601 in UTC.
`transfers[].blockNumber`	integer \| null	The block number.
`transfers[].txHash`	string \| null	The transaction hash.
`transfers[].logIndex`	integer \| null	The event's position in the block.
`transfers[].from`	string \| null	The sender, lowercase — the zero address on a mint.
`transfers[].to`	string \| null	The receiver, lowercase — the zero address on a burn.
`transfers[].kind`	string \| null	`mint` from the zero address, `burn` to it, `transfer` otherwise.
`transfers[].amount`	string \| null	Units moved, as a decimal string: `"1"` for an ERC-721, the count moved for an ERC-1155. `null` for an ERC-1155 on RHC.
`sales`	object[] \| null	Newest first. `null` when `type` is `transfers`. An empty list means no marketplace sale is known.
`sales[].at`	string \| null	Block time, ISO-8601 in UTC.
`sales[].blockNumber`	integer \| null	The block number.
`sales[].txHash`	string \| null	The transaction hash.

`sales[].priceCurrencyAddress`	string \| null	The contract of the token paid, lowercase. `null` when paid in the chain's native coin.
`sales[].itemsInSale`	integer \| null	Tokens sold in the same sale. Above 1, `price` is for all of them, not this one alone.
`hasMore`	boolean	Whether older events exist beyond the 50 listed.
