Zarban SDK

Zarban SDK is a Python interface for interacting with the Zarban DeFi protocol, enabling developers to seamlessly integrate lending and borrowing functionalities into their applications. This SDK simplifies complex DeFi operations by providing easy-to-use methods for lending assets, managing collateral, borrowing funds, and monitoring positions in the Zarban protocol.

Features

• Automated API Client Generation: Built using OpenAPI specification, ensuring type safety and up-to-date API compatibility
• Lending Operations: Easily deposit assets, view lending rates, and manage lending positions
• Borrowing Management: Streamlined methods for borrowing assets, managing collateral, and monitoring loan health
• Position Tracking: Real-time access to user positions, including borrowed amounts, collateral ratios, and liquidation thresholds
• Market Data: Simple methods to fetch current interest rates, available liquidity, and market statistics
• Type Safety: Full type hints support for Python static type checking
• Error Handling: Comprehensive error handling with detailed exceptions for DeFi operations
• Async Support: Asynchronous methods for improved performance in high-throughput applications

Environments

Zarban SDK supports two distinct environments:

1. Mainnet: The production environment for the Zarban DeFi protocol.

   • Wallet API: https://wapi.zarban.io
   • Service API: https://api.zarban.io

2. Testnet: A separate testing environment for the Zarban protocol.

   • Wallet API: https://testwapi.zarban.io
   • Service API: https://testapi.zarban.io

Be sure to use the appropriate environment configuration when interacting with the Zarban SDK.

Installation

pip install zarban

For development installation:

git https://github.com/zarbanio/zarban-py.git
cd zarban-py
pip install -e ".[dev]"

Quick Start

Zarban SDK provides access to two distinct APIs:

1. Wallet API (zarban.wallet)

The Wallet API handles user authentication and wallet management operations.

2. Service API(zarban.service)

The Zarban Service API provides access to core DeFi protocol operations.

import zarban.wallet.openapi_client as wallet

# Initialize the client
cfg         = wallet.Configuration()
api_client  = wallet.ApiClient(cfg)
auth_api    = wallet.AuthApi(api_client)

# Make a simple API call
response = auth_api.some_method()
print(response)

Usage Examples

For detailed usage examples, see our Examples Documentation.

Advanced Usage

Here's a simple example to sign up and get started with Zarban:

import zarban.wallet.openapi_client as wallet


def signup_example():
    # Create and configure the Configuration object
    cfg = wallet.Configuration(
        host="https://testwapi.zarban.io"
    )

    # Create an instance of the ApiClient with the configuration
    api_client = wallet.ApiClient(configuration=cfg)

    # Create an instance of the AuthApi using the api_client
    auth_api = wallet.AuthApi(api_client)

    # Prepare the signup request data
    signup_request = wallet.SignUpRequest(
        email="user@example.com",
        password="yourSecuredPassword",
    )

    try:
        # Call the signup API
        api_response = auth_api.signup_with_email_and_password(signup_request)
        print("Confirmation link sent successfully!")
        print(f"Message: {api_response.messages}")

    except wallet.ApiException as e:
        print(f"Exception when calling auth_api->signup_with_email_and_password: {e}")
        print(f"Error message: {e.body}")

if __name__ == "__main__":
    signup_example()

Configuration

The SDK can be configured with various options to customize its behavior and authentication methods.

Basic Configuration

import zarban.wallet.openapi_client as wallet

# Basic configuration with just the host URL
cfg = wallet.Configuration(host="https://wapi.zarban.io")

Authentication Options

The SDK supports multiple authentication methods:

1. API Key Authentication:

cfg = Configuration(
    host="https://wapi.zarban.io",
    api_key={"APIKeyAuth": "your-api-key-here"},
    # Optional: Add prefix like 'Bearer' for the API key
    api_key_prefix={"APIKeyAuth": "Bearer"}
)

2. Basic Authentication:

cfg = Configuration(
    host="https://wapi.zarban.io",
    username="your-username",
    password="your-password"
)

Advanced Configuration

cfg = Configuration(
    host="https://wapi.zarban.io",
    api_key={"APIKeyAuth": "your-api-key-here"},
    # Discard unknown properties from server responses
    discard_unknown_keys=True
)

Configuration Parameters

Parameter	Type	Description
host	str	Base URL for the API endpoints
api_key	dict	Dictionary of API keys where key is the security scheme name and value is the API key
api_key_prefix	dict	Dictionary of API key prefixes (e.g., "Bearer")
username	str	Username for HTTP basic authentication
password	str	Password for HTTP basic authentication
discard_unknown_keys	bool	Whether to discard unknown properties from server responses

Error Handling

import zarban.service.openapi_client as service

try:
    cfg = service.Configuration(host="https://api.zarban.io")
    api_client = service.ApiClient(cfg)
    stable_coin_system_api = service.StableCoinSystemApi(api_client)
    response = stable_coin_system_api.some_method()
except ApiException as e:
    print(f"An error occurred: {e}")
