Starknet OpenRPC specFor 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.

Parameters

  • request — the details of the function call:
    • contract_address — the address of the contract to be called.
    • entry_point_selector — the selector of the function to be called.
    • calldata — the parameters passed to the function.
  • block_id — the hash of the requested block, or number (height) of the requested block, or a block tag, for the block referencing the state or call the transaction on.

​
Response

  • result — the function’s return value, as defined in the Cairo output.

​
Use case

A practical use case for starknet_call is to interact with a contract’s function without creating a transaction or changing the state. This can be useful for querying contract state or testing function calls.
