Get one NFT's owner/holders
Get ownership for a specific NFT token ID by contract address. Returns the ERC-721 owner or the list of ERC-1155 token holders. Snapshot freshness: ownership comes from materialized snapshots that the data store refreshes every 5 minutes. The ERC-721 ownership snapshot only contains transfers older than head minus 256 blocks, so a newer ERC-721 transfer is not reflected yet; ERC-1155 balances are refreshed every 5 minutes without that cutoff. as_of_block here is the service's current indexed head, not the block height of the snapshot; read the snapshot time from meta.refreshed_at, and treat the data as stale when refreshed_at is null.

Path parameters
Chain identifier: the chain value of an entry in GET /chains (for example robinhood_mainnet), which lists every value this API accepts, i.e. the exact lowercase form of that entry's chain_slug. Matching is exact and case-sensitive; other spellings, aliases and numeric chain IDs are not accepted and return 404 not_found (unknown or not-public chain). What the chain serves differs per chain: see that entry's features and coverage.
20-byte address. 0x/0X prefix optional; either hex digit case is accepted.
20-byte contract address, 0x optional, either case.
Decimal (base-10) integer string, must fit in UInt256. Empty, non-decimal, or out-of-range values are 400.
Response
The ERC-721 owner or ERC-1155 holder list for this (contract, token_id).
