Yes.
We recently added support for the following NFTs that predate the ERC721 standard:
- CryptoKitties
- Cryptopunks
assetType will be set to SPECIAL_NFT for these collections.
This is consistent with our Transfers API.

You can use the collection address (contractAddress) and token id (tokenId) returned in the response to call our getNFTMetadata endpoint - see here.
You can check if the top level error field is null.
You can access the top level gasUsed field.
The API can return a flat or a nested response depending on the 3rd parameter passed in the request (defaults to flat response).
Flat response - gasUsed in first call.
Nested response - gasUsed in root call of nested response.
