A simple Python script to determine the Ethereum gas price that should be used by utilizing the EthGasStation.info API. I use this in simple automation scripts and find it to be more reliable for predicting a safe gas price during congested periods.

getGasPrice.py

#!/usr/bin/env python3

import json
import math
import requests

DEFAULT = 15
MODIFIER = 2

try:
	url = "https://ethgasstation.info/json/ethgasAPI.json"
	r = requests.get(url, timeout=10)
	j = json.loads(r.content.decode("utf-8"))
	g = math.ceil(j["safeLow"] / 10) + MODIFIER
	print(g)
except:
	print(DEFAULT)
