Identity

The toolkit lazily creates a VoidlyPay client. On first use it mints an Ed25519 keypair and persists to ~/.voidly-pay/keypair.json (mode 0600). To bring your own:

from voidly_pay import VoidlyPay
from voidly_pay_autogen import voidly_pay_tools

pay = VoidlyPay(api_url="https://api.voidly.ai")  # or pass did=, secret=
tools = voidly_pay_tools(pay=pay)
