How to get the contract ABI using Starknet.Py?

Hey, to get the contract ABI using StarkNet.py just use the Client's get_class_by_hash method.

However, it requires you to know the contract's class_hash. If you don't know it you will have to use a second method to get it.

Here is a short example of how to get an ABI of your contract.

client = GatewayClient(net="some_net")
address = 0x1234

class_hash = await client.get_class_hash_at(contract_address=address)
abi = (await client.get_class_by_hash(class_hash=class_hash)).abi

You can also go to starkscan.co and see class details. ABI is included there. Example: OpenZeppelin Universal Deployer
