API3 is the native token of the API3 project. It gives its holders the right to take part in the governance of the API3 ecosystem through the API3 DAO. To generate shares in the API3 DAO, token holders have to stake the API3 tokens into the insurance pool, which also gives them access to weekly staking rewards.
