It seems to be an EIP-721 token. Since the code isn't verified one option is to use a wallet like MyEtherWallet that allows interaction with any contract given its address and the contract's ABI.
You could get the ABI from some of the other EIP-721 contracts from the etherscan page. Calling the standard methods like tokenUri shouldn't be a problem.
In that particular address 0x3cd266509d127d0eac42f4474f57d0526804b44e I got https://tokens.buildspace.so/assets/CH21b8c9cb-617a-4762-aef4-15147e15513d-25/metadata.json for tokenId 999.
If that fails you could call the other NFT standard EIP-1155.
