Python SDK

The official async Python SDK for the Crypto Chief crypto processing API — accept payments, send payouts, sign transactions, and verify webhooks across 25+ chains.

The official asyncio client for the Crypto Chief crypto processing API. One install gives you fully typed access to payments, payouts, on-chain transactions, wallets, and webhooks across 25+ chains.

PyPI

Requirements

  • Python 3.10+

  • A Crypto Chief Merchant ID and API key (Dashboard → Integration)

Installation

pip install cryptochief-crypto-processing-python
from cryptochief import CryptoChiefClient, Chain

The package is async-first (built on httpx) and fully typed — requests and responses are dataclasses, and the field names match the REST API exactly, so there is no camelCase translation layer to learn.

Quickstart

import asyncio
from cryptochief import CryptoChiefClient, Chain, EstimatePayoutRequest

async def main():
    async with CryptoChiefClient(
        merchant_id="MERCHANT_ID",
        api_key="API_KEY",
    ) as client:
        est = await client.payouts.estimate(EstimatePayoutRequest(
            network=Chain.ETH_SEPOLIA,
            coin="ETH",
            amount="0.0001",
            to_address="0xRecipient...",
        ))
        print("amount to receive:", est.amount_to_receive)

asyncio.run(main())

If estimate resolves without raising, your credentials and request signing are working end-to-end.
