# Module API

Each module in Miyabi provides additional endpoints. To verify if a module is correctly loaded, swagger has a list of the ones supported.

# Definition of Terms

Term	Definition
Asset Table	Is used to store a user assets in an address. In order to move assets between addresses, the signature of the owner is needed. If the table has a Trusted address defined, the owner of Trusted address can move assets from other addresses to its own using its signature. Generation of assets can only be done if they are signed by the table owner.
Entity Table	Is used to store the data of users in binary key value pairs. This table supports a way to manage the relationships between different rows of pairs so a user can store arbitrary values separately. Also, it can implement a permissioned row table, which combined with the mentioned relationships, can have sets of data with different permissions for each user.
Entity Owner	Is the individual that owns a particular row in an entity table. If an entity does not have an owner, it can only be accessed by the update admin.
