You must include the following args

key	value
contract_address	Your contract address to verify
contract_name	Your contract name to verify
compiler_version	Compiler version, e.g. v0.8.25+commit.b61c2a91
chain	Put your chain id (Not required)
verifier-url	<api_host>/v1/explorer/command_api/contract API Host: https://api.socialscan.io/<chain_name>/
verifier	Use "blockscout" or "etherscan"
etherscan-api-key	If you use "etherscan" as a verifier, you need to put a random string here
