Starknet OpenRPC spec
For the latest version of the publicly maintained OpenRPC spec, see the Starknet specs GitHub repo.
Starknet API method that executes a function call to a contract without creating a Starknet transaction.
It allows you to call a function in a contract and returns the value of the function that you run on the contract. Using this call will not create a transaction; hence, it will not change the state.
