circle-web3-sdk-util 9.4.1

The Python SDK Utility for Circle Web3 Services

Circle Web3 APIs Python SDK

The Circle Web3 Python SDK provides convenient access to the Circle Web3 APIs for applications written in Python. For the API reference, see the Circle Web3 API Docs.

PyPI packages:

• circle-developer-controlled-wallets
• circle-smart-contract-platform
• circle-user-controlled-wallets
• circle-configurations — base client (installed transitively by the others)

Requirements

Python 3.10+.

Installation

Install one or more of the SDK packages from PyPI:

pip install circle-developer-controlled-wallets
pip install circle-smart-contract-platform
pip install circle-user-controlled-wallets

Usage

Secure your API key and entity secret by setting them as environment variables. See the entity secret management guide for details.

export CIRCLE_WEB3_API_KEY="Your API KEY"
export CIRCLE_ENTITY_SECRET="Your entity secret"

Initialize the clients:

from circle.web3 import utils

dcw_client = utils.init_developer_controlled_wallets_client(api_key="Your API KEY", entity_secret="Your entity secret")
scp_client = utils.init_smart_contract_platform_client(api_key="Your API KEY", entity_secret="Your entity secret")
ucw_client = utils.init_user_controlled_wallets_client(api_key="Your API KEY")

Make a request:

from circle.web3 import user_controlled_wallets, utils

ucw_client = utils.init_user_controlled_wallets_client(api_key="<your-api-key>")

api_instance = user_controlled_wallets.PINAuthenticationApi(ucw_client)
try:
    api_request = user_controlled_wallets.UserTokenRequest.from_dict({"userId": "test-user"})
    api_response = api_instance.get_user_token(api_request)
    print(api_response.data.user_token)
except user_controlled_wallets.ApiException as e:
    print("Exception when calling PINAuthenticationApi->get_user_token: %s\n" % e)
