A simple script to extract your helium node's penalty history. Offers a little more history than is available on the website.

validator-penalties.js

// you'll need to run ```npm i lodash cross-fetch``` first to install the packages
// next, to run it: ```node validator-penalties.js "your-node-name"```
// this script assumes no collisions in node names, which does occur in the wild
const _ = require('lodash');
const fetch = require('cross-fetch');
const findMe = process.argv[2];

(async () => {
    try {

        const res = await fetch(`https://explorer-api.helium.com/api/validators`);

        if (res.status >= 400) {
            throw new Error("Bad response from server");
        }

        const validators = await res.json();
        console.log(`res.status is ${res.status}`);
        
        const theCatch = _.find(validators,(validator) => {
            return validator.name === findMe;
        });
        const penalties = theCatch.penalties;
        
        console.table(penalties);
    } catch (err) {
        console.error(err);
    }
})();
