realtimex_toolkit 1.2.0

Lightweight internal utilities for LLM provider configuration and credential management

RealtimeX Internal Utilities

Lightweight internal library providing utilities for LLM provider configuration and credential management across RealtimeX internal services.

Installation

# Using uv (recommended) for local development
uv pip install -e /path/to/realtimex-toolkit

# Using pip from PyPI
pip install realtimex_toolkit

Quick Start

Agent Flow Management

Work with agent flow data. get_flow_variable now supports dotted paths for nested structures, safe defaults, and fetching the full payload.

import json

from realtimex_toolkit import get_flow_variable

# Access nested variables using dotted notation
user_email = get_flow_variable("user.email")
print(user_email)  # "[e-mail]"

# Provide defaults for missing keys
theme = get_flow_variable("user.theme", "light")
print(theme)  # "light"

# Get the entire payload when you need to inspect everything
variables = get_flow_variable()
print(json.dumps(variables))  # {"time":"12:40:28 PM", ...}

Credential Management

Retrieve encrypted credentials from the RealtimeX app backend and decrypt them for use across RealtimeX ecosystem services.

from realtimex_toolkit import get_credential

# Simplest usage - just the credential ID
# Connects to local RealtimeX backend (http://localhost:3001) by default
credential = get_credential("credential-id")
print(credential["payload"])  # {"name": "API_KEY", "value": "secret-value"}

# With API key for authenticated requests
credential = get_credential("credential-id", api_key="service-api-key")

# With custom backend URL (for non-default configurations)
credential = get_credential(
    "credential-id",
    api_key="service-api-key",
    base_url="http://custom-host:3001"  # Override default localhost:3001
)

# For long-running services, use CredentialManager directly
from realtimex_toolkit import CredentialManager

# Connects to http://localhost:3001 by default
manager = CredentialManager(api_key="service-api-key")
try:
    bundle = manager.get("credential-id")
    # Credentials are cached automatically
    bundle_again = manager.get("credential-id")  # Returns cached

    # Force refresh from backend
    fresh_bundle = manager.get("credential-id", force_refresh=True)
finally:
    manager.close()

Configuration:

• base_url: Base URL of the RealtimeX app backend (default: http://localhost:3001)
• api_key: Authentication token for backend API requests (optional)
• Credentials are encrypted using AES-256-CBC and decrypted using keys from ~/.realtimex.ai/Resources/server/.env.development

Return shape (get_credential):

{
    "credential_id": str,
    "name": str,
    "credential_type": str,
    "payload": dict[str, str],
    "metadata": dict | None,
    "updated_at": str | None,
}
