Explorer Api

the explorer api is a documentation of the api of the caduceus browser explorer you can find the explorer here https //cmpscan io/miscapis where you will be able to sign up, verify contracts and query the blockchain, helping you query data that is specific to nft's or erc20 tokens you can also get the log events or verify a contract via api you must sign up at cmpscan io to get an api key account
