## Output Types

The API supports three types of outputs, which can be identified by the `type` field in the decoded data or filtered using the `output_type` parameter in list queries:

- `0xc258d6e5`: **Notice** – Informational messages emitted by the application.
- `0x237a816f`: **Voucher** – Single-use permission to execute a call.
- `0x10321e8b`: **DelegateCallVoucher** – Single-use permission to execute a DELEGATECALL.
