# Contract APIs

This section contains an enumeration of the available smart-contract APIs that can developers can use in their applications on and off-chain. These functions are primarily useful for two functions:

* Writing Stork signed updates for specific assets to the contract - typically from off-chain applications
* Reading latest values for specific assets from the contract - typically from on-chain applications

The following APIs are available for supported chains:
