[User] Which NFTs minted in the past 14 days on Ethereum have a rarity_score above 70? For each, show contract address, token ID, name, and minter.

[Assistant]
SELECT contract_address, token_id, name, minter
FROM nft_metadata
WHERE blockchain = 'Ethereum'
  AND mint_time >= (extract(epoch from now()) - 14*24*60*60)
  AND rarity_score > 70;

[User] For these NFTs, can you also include the collection name and symbol by joining with the nft_collections table?

[Assistant]
SELECT nm.contract_address, nm.token_id, nm.name, nm.minter, nc.name AS collection_name, nc.symbol
FROM nft_metadata nm
JOIN nft_collections nc
  ON nm.blockchain = nc.blockchain AND nm.contract_address = nc.contract_address
WHERE nm.blockchain = 'Ethereum'
  AND nm.mint_time >= (extract(epoch from now()) - 14*24*60*60)
  AND nm.rarity_score > 70;

[User] Can you filter only those collections where the erc_type is 'ERC1155'?

[Assistant]
SELECT nm.contract_address, nm.token_id, nm.name, nm.minter, nc.name AS collection_name, nc.symbol
FROM nft_metadata nm
JOIN nft_collections nc
  ON nm.blockchain = nc.blockchain AND nm.contract_address = nc.contract_address
WHERE nm.blockchain = 'Ethereum'
  AND nm.mint_time >= (extract(epoch from now()) - 14*24*60*60)
  AND nm.rarity_score > 70
  AND nc.erc_type = 'ERC1155';

[User] Now, also include the owner for each NFT, and order the results by rarity_rank ascending.

[Assistant]
SELECT nm.contract_address, nm.token_id, nm.name, nm.minter, nm.owner, nc.name AS collection_name, nc.symbol
FROM nft_metadata nm
JOIN nft_collections nc
  ON nm.blockchain = nc.blockchain AND nm.contract_address = nc.contract_address
WHERE nm.blockchain = 'Ethereum'
  AND nm.mint_time >= (extract(epoch from now()) - 14*24*60*60)
  AND nm.rarity_score > 70
  AND nc.erc_type = 'ERC1155'
ORDER BY nm.rarity_rank ASC;

[Assistant] SELECT transfer_id, token_id, transaction_id, value FROM web3.token_transfers WHERE value > 1000;
