arp-standard-client 0.2.2

Python client package for the ARP Standard (v1).

ARP Standard Python Client (arp-standard-client)

Install

python3 -m pip install arp-standard-client

Usage

from arp_standard_client.daemon import DaemonClient
from arp_standard_model import (
    DaemonCreateInstancesRequest,
    DaemonHealthRequest,
    DaemonListInstancesRequest,
    DaemonListRunsParams,
    DaemonListRunsRequest,
    InstanceCreateRequestBody,
)

client = DaemonClient(base_url="http://127.0.0.1:8082")
health = client.health(DaemonHealthRequest())
instances = client.list_instances(DaemonListInstancesRequest())
created = client.create_instances(
    DaemonCreateInstancesRequest(
        body=InstanceCreateRequestBody(runtime_profile="default", count=1)
    )
)
runs = client.list_runs(DaemonListRunsRequest(params=DaemonListRunsParams(page_size=50)))

Request objects

All facade methods require a single request object from arp_standard_model. These request objects wrap:

• params: path/query parameters (if any)
• body: JSON request body (if any)

Request and params models are service-prefixed (e.g., DaemonListRunsRequest, RuntimeGetRunStatusRequest) to avoid collisions. Request body models are also exported with a *RequestBody alias (e.g., InstanceCreateRequestBody).

Wire format

Models use the exact JSON field names from the spec (no aliasing). When serializing manually, use model_dump(exclude_none=True).

Authentication (API key)

client = DaemonClient(
    base_url="http://127.0.0.1:8082",
    headers={"X-API-Key": "your-api-key"},
)

Streaming (NDJSON)

Streaming endpoints currently return NDJSON as plain text. Helpers are planned but not implemented yet.

from arp_standard_client.runtime import RuntimeClient
from arp_standard_model import RuntimeStreamRunEventsParams, RuntimeStreamRunEventsRequest

runtime = RuntimeClient(base_url="http://127.0.0.1:8081")
text = runtime.get_run_events(
    RuntimeStreamRunEventsRequest(params=RuntimeStreamRunEventsParams(run_id=run_id))
)
for line in text.splitlines():
    if not line:
        continue
    # json.loads(line)

Spec reference

arp_standard_client.SPEC_REF exposes the spec tag (for example, spec/v1@v0.2.2) used to generate the package.
