realtimex_toolkit 1.1.0

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)
uv pip install -e /path/to/realtimex-toolkit

# Using pip
pip install -e /path/to/realtimex-toolkit

Quick Start

LLM Provider Configuration

from realtimex import configure_provider, get_provider_env_vars

# Configure provider (sets environment variables)
env_vars = configure_provider("openai")

# Get provider env vars without setting them
env_vars = get_provider_env_vars("openai")

# With explicit providers
env_vars = configure_provider(
    "openai",
    providers={"openai": {"OPEN_AI_KEY": "sk-..."}}
)

Credential Management

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

from realtimex 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 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,
}
