Python

The Python SDK is the Python client for the antd daemon.

Install

pip install antd[rest]
pip install antd[grpc]
pip install antd[all]

Connect to the daemon

from antd import AntdClient, AsyncAntdClient, discover_daemon_url

# REST transport by default
client = AntdClient()

# Async REST client
async_client = AsyncAntdClient()

# Explicit gRPC transport
grpc_client = AntdClient(transport="grpc", target="localhost:50051")

# Use discovery helpers if antd chose a non-default port
base_url = discover_daemon_url() or "http://localhost:8082"
discovered_client = AntdClient(base_url=base_url)

Store and retrieve data

For upload examples in this section, start antd in a write-enabled mode first. On the default network, that means wallet plus EVM payment configuration. On a local devnet, ant dev start provisions that for you.

from antd import AntdClient

client = AntdClient()
status = client.health()
assert status.ok

result = client.data_put_public(b"Hello from Python!")
print(result.address)

data = client.data_get_public(result.address)
assert data == b"Hello from Python!"
print(data.decode())

Type mappings

Autonomi type	Python type
HealthStatus	antd.HealthStatus
PutResult	antd.PutResult
WalletAddress	antd.WalletAddress
WalletBalance	antd.WalletBalance
PrepareUploadResult	antd.PrepareUploadResult
FinalizeUploadResult	antd.FinalizeUploadResult
Raw data	bytes

Error handling

from antd import AntdClient, AntdError, NotFoundError, PaymentError

client = AntdClient()

try:
    client.data_get_public("nonexistent_address")
except NotFoundError:
    print("Data not found")
except PaymentError:
    print("Insufficient funds")
except AntdError as error:
    print(error)

REST and gRPC share the same high-level API, but wallet operations and payment_mode are REST-only.
