Token Contract
nft_address
It describes the NFT contract address which is approved.
Chain

The chain_id of the blockchain.
"1" means Ethereum;
"56" means BSC.
NFT Name
nft_name
token_name

token_symbol
Open Source
is_open_source
It describes whether this contract is open source.
"1" means true;
"0" means false.
Un-open-sourced contracts may hide various unknown mechanisms and are extremely risky.
When the contract is not open source, we will not be able to detect other risk items.
The NFT verified

It describes whether the NFT is verified.
"1" means that the NFT is verified;
"0" means that we did not find any information about whether the NFT is verified.
Malicious NFT
malicious_address
It describes whether this token has performed malicious behaviors.
"1" means true;
"2" means false.
Malicious behaviors include random additions, blacklist abuse, falsified transactions, and other high-risk behaviors. Interacting with tokens flagged as Malicious may contain a high level of risk.
Specific Malicious Behavior
malicious_behavior:[]
It describes specific malicious behaviors. "honeypot_related_address" means that the address is related to honeypot tokens or has created scam tokens. "phishing_activities" means that this address has implemented phishing activities. "blackmail_activities" means that this address has implemented blackmail activities. "stealing_attack" means that this address has implemented stealing attacks. "fake_kyc" means that this address is involved in fake KYC. "malicious_mining_activities" means that this address is involved in malicious mining activities. "darkweb_transactions" means that this address is involved in darkweb transactions. "cybercrime" means that this address is involved in cybercrime. "money_laundering" means that this address is involved in money laundering. "financial_crime" means that this address is involved in financial crime. “blacklist_doubt” means that the address is suspected of malicious behavior and is therefore blacklisted
Returning an empty array means that no malicious behavior was found at that address.
Approved Contract

It describes the approved contract.
Latest Approved Time
approved_time
It describes the latest allowance changeing time of the contract.
The value is presented as a timestamp.
Latest Approved Hash
hash
It describes the latest allowance changeing hash of the contract.
Approved Type(Approved for all /Approved for single NFT)
approved_for_all
It describes the type approved.
"1" means "approved for all";
"0" means "approved for single NFT".
The type of return value is bool.Note: Only the ERC721 NFTs have the two types of approved for all /approved for single.
The ERC1155 NFTs have only one type - approved for all.
The Token_id of Approved NFT
approved_token_id
It describes the token_id of the approved NFT if the approved type is "approved for single".
When the approved type is "approved for all" ("approved_for_all"=1), it will return "null".
