Python bindings for Rango Exchange Main API

Python SDK for Rango Exchange Main API

Rango Aggregation APIs for dApps and Wallets for cross-chain and on-chain swaps using the best route from all of the available on-chain liquidity protocols, getting multichain balance/portfolio for user wallets, and easiest method to transfer tokens across all blockchain networks.

Requirements

This package supports Python 3.8 and newer.

Installation

Install it with:

python -m pip install rango-sdk-py

Alternatively, install from the source code with this command from the project root:

python -m pip install .

For an editable installation while developing:

python -m pip install -e .

Usage

Synchronous client

Client is the synchronous API. Close it when finished, or use a with block.

from decimal import Decimal

from rango_sdk import Client, models

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.routing.get_best_route(body=models.SingleRouteRequest(from_=models.RequestAsset(blockchain=models.Blockchain.ETH, symbol="ETH"), to=models.RequestAsset(blockchain=models.Blockchain.AVAX_CCHAIN, symbol="USDT.E", address="0xc7198437980c041c805a1edcba50c1ce5db95118"), amount=Decimal("0.28")))

Endpoints are nested under attributes (see client.py):

• client.balance → BalanceOperations
• client.metadata → MetadataOperations
• client.multi_routing → MultiRoutingOperations
• client.routing → RoutingOperations
• client.transaction → TransactionOperations

Asynchronous client

AsyncClient is the asynchronous API. Use async with and await each call.

import asyncio
from decimal import Decimal

from rango_sdk import AsyncClient, models

async def main() -> None:
    async with AsyncClient(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
        result = await client.routing.get_best_route(body=models.SingleRouteRequest(from_=models.RequestAsset(blockchain=models.Blockchain.ETH, symbol="ETH"), to=models.RequestAsset(blockchain=models.Blockchain.AVAX_CCHAIN, symbol="USDT.E", address="0xc7198437980c041c805a1edcba50c1ce5db95118"), amount=Decimal("0.28")))

asyncio.run(main())

Authentication

The Usage section above and the examples/ / docs/ trees show authentication via constructor keyword arguments; This package also supports environment-variable credentials (using RANGO prefix for env vars).

apiKey — API key (query parameter)

• This sdk uses apiKey auth: the credential is sent as the query parameter apiKey.
• Use constructor option api_key.
• Pass these as keyword arguments to Client(...) / AsyncClient(...).
• Alternatively set environment variable RANGO_API_KEY. Explicit constructor options override env when both are set.

For private or production authentication parameters, contact Rango via [e-mail] or https://t.me/rangoexchange. See the official API documentation.

Example Codes

The examples below show only the most commonly used endpoints to help you get started quickly.

For advanced usage and less common operations, consult the API Reference.

Get Balance of a Token

Fetches the balance of a specific token address for the user's wallet

Runnable source: get_token_balance.py

from rango_sdk import Client, models

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.balance.get_token_balance(wallet_address="0x9F8cCdaFCc39F3c7D6EBf637c9151673CBc36b88", blockchain=models.Blockchain.BSC, symbol="USDT", address="0x55d398326f99059ff775485246999027b3197955")
    print(result)

Get the Best Swap Route

Get the best route to perform a cross-chain or same-chain swap, the requestId parameter from the response of this endpoint will be used for creating the transaction and checking the transaction status in next steps

Runnable source: get_best_route.py

from decimal import Decimal
from rango_sdk import Client, models

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.routing.get_best_route(body=models.SingleRouteRequest(from_=models.RequestAsset(blockchain=models.Blockchain.ETH, symbol="ETH"), to=models.RequestAsset(blockchain=models.Blockchain.AVAX_CCHAIN, symbol="USDT.E", address="0xc7198437980c041c805a1edcba50c1ce5db95118"), amount=Decimal("0.28")))
    print(result)

Create the Transaction

Creates a transaction to be signed by user's wallet and broadcasted to the network

Runnable source: create_transaction.py

from decimal import Decimal
from rango_sdk import Client, models

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.transaction.create_transaction(body=models.CreateTransactionRequest(request_id="1978d8fa-335d-4915-a039-77f1a17315f5", step=1, user_settings=models.UserSettings(slippage=Decimal("8.25"), use_max_native_token_balance=False), validations=models.CreateTransactionValidation(balance=True, fee=True, approve=True)))
    print(result)

Check the Transaction Status

Checks the status of the transaction using the requestId from the quote/route and the broadcasted transaction hash (txId)

Runnable source: check_tx_status.py

from rango_sdk import Client, models

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.transaction.check_tx_status(body=models.CheckTxStatusRequest(request_id="b3a12c6d-86b8-4c21-97e4-809151dd4036", tx_id="0xfa88b705a5b4049adac7caff50c887d9600ef023ef1a937f8f8b6f44e90042b5", step=1))
    print(result)
