If you think that a newly-added method is missing, kindly open an issue as a feature request and I will do my best to add it.

Installation

Before proceeding, you should register an account on etherscan.io and generate a personal API key to use.

Assuming conda is already installed on your system, first create the environment:

conda env create -f env.yml

Activate the environment:

conda activate etherscan-python

Then, install the package:

pip install .

Run unittests

Test that everything looks OK on your end before proceeding:

coverage run -m unittest discover && coverage report -m

This will regenerate the logs under logs/ with the most recent results and the timestamp of the execution.

Usage

In python, create a client with your personal etherscan.io API key:

from etherscan import Etherscan  api_key = YOUR_API_KEY config_path = "etherscan/configs/stable.json"  eth = Etherscan.from_config(config_path, api_key)

Then you can call all available methods, e.g.:

eth.get_eth_balance(address="0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a")  > '40891631566070000000000'

Examples

Examples (arguments and results) for all methods may be found as JSON files here. For example, if you want to use the method get_block_number_by_timestamp, you can find the supported arguments and the format of its output in its respective JSON file:

{   "method": "get_block_number_by_timestamp",   "module": "blocks",   "kwargs": {     "timestamp": "1578638524",     "closest": "before"   },   "log_timestamp": "2020-09-30-15:39:18",   "res": "9251482" }

where kwargs refer to the required named arguments and res refers to the expected result if you were to run:

eth.get_block_number_by_timestamp(timestamp="1578638524", closest="before")  > '9251482'

Disclaimer: Those examples blindly use the arguments originally showcased here and the selected wallets/contracts do not reflect any personal preference. You should refer to the same source for additional information regarding specific argument values.

Issues

For problems regarding installing or using the package please open an issue. Kindly avoid disclosing potentially sensitive information such as your API keys or your wallet addresses.

Installation

Before proceeding, you should register an account on etherscan.io and generate a personal API key to use.

Assuming conda is already installed on your system, first create the environment:

conda env create -f env.yml
conda activate etherscan-python

继续之前，您应该在上注册一个帐户以太网扫描.io并生成一个要使用的个人API密钥。

pip install .

Run unittests

假设系统上已经安装了conda，首先创建环境：

coverage run -m unittest discover && coverage report -m

激活环境：

Usage

然后，安装程序包：

from etherscan import Etherscan  api_key = YOUR_API_KEY config_path = "etherscan/configs/stable.json"  eth = Etherscan.from_config(config_path, api_key)

在继续之前，测试您的端部是否一切正常：

eth.get_eth_balance(address="0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a")  > '40891631566070000000000'

Examples

这将使用最新的结果和执行的时间戳在logs/下重新生成日志。

{   "method": "get_block_number_by_timestamp",   "module": "blocks",   "kwargs": {     "timestamp": "1578638524",     "closest": "before"   },   "log_timestamp": "2020-09-30-15:39:18",   "res": "9251482" }

在python中，使用您的个人以太网扫描.ioAPI键：

eth.get_block_number_by_timestamp(timestamp="1578638524", closest="before")  > '9251482'

然后您可以调用所有可用的方法，例如：

Issues

所有方法的示例（参数和结果）都可以在这里找到JSON文件。例如，如果要使用get_block_number_by_timestamp方法，您可以在其各自的JSON文件中找到支持的参数及其输出格式：

其中kwargs表示必需的命名参数，res表示运行时的预期结果：

免责声明：这些示例盲目使用此处最初显示的参数，而选定的钱包/合同则不使用反映个人喜好。有关特定参数值的其他信息，请参阅同一源。
