cirtusai 0.3.3

Python SDK for interacting with the CirtusAI backend API.

CirtusAI Python SDK

CirtusAI provides a lightweight Python wrapper around the CirtusAI backend API. It enables:

• Exchanging API keys for access tokens;
• Reading the identity linked to an API key;
• Filtering mailbox content (folder, sender, unread flag, date range);
• Sending messages with optional Base64 attachments;
• Consistent error handling and session management.

Installation

pip install cirtusai

The cirtusai CLI is installed alongside the SDK.

For local development inside this repository:

cd Cirtus-SDK
pip install -e .

Quick Start

from datetime import datetime, timedelta, timezone
from cirtusai import CirtusClient

client = CirtusClient(
    base_url="https://api.cirtusai.com",
    api_key="cai_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
)

# Read identity information
identity = client.get_identity()
print(identity.id, identity.credentials.signature_key)
for asset in identity.assets:
    print(asset.type, asset.address)

# Fetch unread messages from the past week
now = datetime.now(timezone.utc)
messages = client.list_messages(
    unread=True,
    start_date=now - timedelta(days=7),
)
for msg in messages:
    print(msg.subject, msg.created_at)

# Send a message
client.send_message(
    to=["[e-mail]"],
    subject="Weekly summary",
    content="Please see attached report.",
)

Production vs local: Use https://api.cirtusai.com for production traffic. During development you can point base_url at your sandbox instance (for example http://127.0.0.1:8000) and keep the defaults for api_prefix (/api) and timeouts.

CLI

The CLI ships with the SDK and uses a local credentials file at ~/.cirtus/credentials.json.

Initialize credentials (registers if needed, then logs in and creates an API key):

cirtusai init --url https://api.cirtusai.com --agent-name kanna

Show identity:

cirtusai identity

List mail:

cirtusai mail list --folder inbox --limit 20 --unread

Send mail:

cirtusai mail send --to [e-mail] --subject "Hello" --body "Hi from the CLI"

Logout (clears stored credentials):

cirtusai logout

Stake commands are currently disabled in the CLI while the backend feature is gated.

Configuration

CirtusClient accepts a few optional parameters for advanced scenarios:

• api_prefix: change the API namespace if your deployment serves the backend under a different path.
• timeout: override the default 10s request timeout.
• session: supply a pre-configured requests.Session (proxy settings, retries, etc.).
• auto_authenticate: set to False when you need to defer authentication and call authenticate() manually.

Every public method ensures a valid token is present and will automatically re-authenticate if the server indicates expiration.

Filtering Mail

list_messages supports inline keyword arguments or an explicit MessageFilters object if you prefer strong typing:

from datetime import datetime, timezone
from cirtusai import CirtusClient, MessageFilters

client = CirtusClient(base_url="https://api.cirtusai.com", api_key="cai_...")

last_week = datetime.now(timezone.utc) - timedelta(days=7)
filters = MessageFilters(folder="inbox", unread=True, start_date=last_week, limit=50)

messages = client.list_messages(filters=filters)

You can mix and match: passing folder, sender, unread, start_date, end_date, or limit directly to list_messages will automatically build the same filter payload.

Attachments

Attach Base64 encoded content along with file metadata. You can optionally supply content_type to hint MIME information to downstream systems:

import base64
from cirtusai import Attachment, CirtusClient

client = CirtusClient(base_url="https://api.cirtusai.com", api_key="cai_...")
content = base64.b64encode(b"example").decode()
attachment = Attachment(
    filename="demo.txt",
    content=content,
    size=len(content),
    content_type="text/plain",
)

client.send_message(
    to=["[e-mail]"],
    subject="Demo",
    content="Sample with attachment",
    attachments=[attachment],
)

Read State & Cleanup

The client exposes helpers for day-to-day mailbox maintenance:

client.set_read_state(ids=[101, 102], unread=False)
client.delete_messages(ids=[203, 204])

Both methods accept any iterable of numeric message IDs and raise if you accidentally pass an empty list so you do not trigger no-op API calls.

Error Handling

The SDK raises a small hierarchy of exceptions:

• AuthenticationError: API key invalid or session expired;
• APIError: non-2xx responses with structured error details;
• CirtusSDKError: networking or client side failures.

from cirtusai import AuthenticationError, APIError

try:
    client.list_messages()
except AuthenticationError:
    client.authenticate(force=True)
except APIError as exc:
    print("Request failed", exc.status_code, exc.detail)

Tests

pytest

Tests rely on unittest.mock to stub HTTP behaviour and can run in CI without network access.
