open-spanner

Python client for the Open Spanner API.

Install from PyPI:

pip install open-spanner

Record usage for a meter that already exists:

from datetime import UTC, datetime
from uuid import uuid4

from open_spanner_client import AuthenticatedClient
from open_spanner_client.api.usages import create_usage
from open_spanner_client.models.usage_create_request import UsageCreateRequest

api_key = "..."

client = AuthenticatedClient(
    base_url="https://api.example.com",
    token=api_key,
    raise_on_unexpected_status=True,
)

usage = create_usage.sync(
    client=client,
    body=UsageCreateRequest(
        idempotency_key=str(uuid4()),
        subject="org_123",
        meter="api_requests",
        quantity=1,
        timestamp=datetime.now(UTC).isoformat(),
    ),
)

print(usage.id)

Stream usage over gRPC:

from datetime import UTC, datetime

from open_spanner_client.stream import Event, StreamClient

client = StreamClient("localhost:18090", "osp_...")
try:
    result = client.track_bulk(
        "batch-1",
        [
            Event(
                idempotency_key="usage-1",
                subject="org_123",
                meter="api_requests",
                quantity=1,
                timestamp=datetime.now(UTC),
                metadata={"endpoint": "/v1/orders", "status": 200},
            )
        ],
    )
finally:
    client.close()

print(result.accepted_count)
