Unfortunately, you cannot tell from the vault Apr whether or not a contract is active. To check the status of a contract, you would need to look up the contract address and view the details of the transaction. You can use a blockchain explorer such as Etherscan to do this. Etherscan will provide you with information such as the transaction ID, block number, and other details related to the contract. Additionally, you can use the Etherscan API to programmatically query the blockchain for contract details.
