rango-basic-sdk 0.0.3

Python bindings for Rango Exchange Basic API

Python SDK for Rango Exchange Basic API

Simple and Easy to use APIs for Rango Aggregation protocols for dApps and Wallets for single step cross-chain and on-chain swaps using the best route and all the available on-chain liquidity across all blockchain networks.

Requirements

This package supports Python 3.8 and newer.

Installation

Install it with:

python -m pip install rango-basic-sdk

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 rango_basic_sdk import Client

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.routing.quote(from_="BSC.BNB", to="AVAX_CCHAIN.USDT.E--0xc7198437980c041c805a1edcba50c1ce5db95118", amount=10000000000000000, slippage=3.5)

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

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

Asynchronous client

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

import asyncio
from rango_basic_sdk import AsyncClient

async def main() -> None:
    async with AsyncClient(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
        result = await client.routing.quote(from_="BSC.BNB", to="AVAX_CCHAIN.USDT.E--0xc7198437980c041c805a1edcba50c1ce5db95118", amount=10000000000000000, slippage=3.5)

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_BASIC 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_BASIC_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.

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_basic_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 Quote for swapping

Get the best route to perform a cross-chain or same-chain swap

Runnable source: quote.py

from rango_basic_sdk import Client

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.routing.quote(from_="BSC.BNB", to="AVAX_CCHAIN.USDT.E--0xc7198437980c041c805a1edcba50c1ce5db95118", amount=10000000000000000, slippage=3.5)
    print(result)

Create the Transaction (Swap)

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

Runnable source: swap.py

from rango_basic_sdk import Client

with Client(api_key='c6381a79-2817-4602-83bf-6a641a409e32') as client:
    result = client.transaction.swap(from_="BSC.BNB", to="AVAX_CCHAIN.USDT.E--0xc7198437980c041c805a1edcba50c1ce5db95118", amount=10000000000000000, slippage=3.5, from_address="0x9F8cCdaFCc39F3c7D6EBf637c9151673CBc36b88", to_address="0x6f33bb1763eebead07cf8815a62fcd7b30311fa3", disable_estimate=False, infinite_approve=False)
    print(result)

Check the Transaction Status

Checks the status of the transaction using the requestId from the swap endpoint and the broadcasted transaction hash (txId)

Runnable source: status.py

from rango_basic_sdk import Client

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

Additional samples for all endpoints live under the examples/ folder.

HTTP debug logging

To print each HTTP request and response (method, URL, status, headers, and bodies) after the response is received, pass log_http_debug=True to Client or AsyncClient, and set the rango_basic_sdk.client logger to DEBUG so those messages are emitted.

Bodies are truncated after 16 KiB per direction. Do not use this in production or with real secrets: debug output can include credentials (e.g. Authorization, API keys, cookies).

import logging

from rango_basic_sdk import Client

logging.getLogger("rango_basic_sdk.client").setLevel(logging.DEBUG)
if not logging.root.handlers:
    logging.basicConfig(level=logging.DEBUG)

with Client(log_http_debug=True) as client:
    # …
    pass

For AsyncClient, use the same logging setup and AsyncClient(log_http_debug=True, ...).
