_In this tutorial, we will show how to interpret account reputation_

This tutorial runs on the main Steem blockchain. And accounts queried are real users with reputation.

This tutorial will show the method of capturing a queried tag name and matching it to the Steem. We are using the `call` function provided by the `dsteem` library to pull accounts from the Steem blockchain. A simple HTML interface is used to both capture the string query as well as display the completed search.

1. [**App setup**](#app-setup) Configuration of `dsteem` to use the proper connection and network.

2. [**Search account**](#search-account) Collecting the relevant search criteria

3. [**Interpret account reputation**](#run-reputation) Running the search and interpreting reputation.

4. [**Output**](#output) Displaying the results

Below we have `dsteem` pointing to the production network with the proper chainId, addressPrefix, and endpoint. There is a `public/app.js` file which holds the Javascript segment of this tutorial. In the first few lines we define the configured library and packages:

const dsteem = require('dsteem');

let opts = {};

opts.addressPrefix = 'STM';

opts.chainId =

'0000000000000000000000000000000000000000000000000000000000000000';

const client = new dsteem.Client('https://api.steemit.com');

Collecting of the search criteria happens via an HTML input. The form can be found in the `index.html` file. The values are pulled from that screen with the below:

const max = 5;

window.submitAcc = async () => {

const accSearch = document.getElementById('username').value;

In order to get accounts, we run the search with the `search field` and `maximum` list items as parameters.

```javascript

const _accounts = await client.database.call('lookup_accounts',[accSearch, max]);

The result of the search is an array of accounts. After that we use `get_accounts` to pull account data from Steem.

```javascript

const acc = await client.database.call('get_accounts',[_accounts]);

And we loop through each account to convert their `reputation` to human readable format with following function:

```javascript

function log10(str) {

const leadingDigits = parseInt(str.substring(0, 4));

const log = Math.log(leadingDigits) / Math.LN10 + 0.00000001;

const n = str.length - 1;

return n + (log - parseInt(log));

}

export const repLog10 = rep2 => {

if (rep2 == null) return rep2;

let rep = String(rep2);

const neg = rep.charAt(0) === '-';

rep = neg ? rep.substring(1) : rep;

let out = log10(rep);

if (isNaN(out)) out = 0;

out = Math.max(out - 9, 0); // @ -9, $0.50 earned is approx magnitude 1

out = (neg ? -1 : 1) * out;

out = out * 9 + 25; // 9 points per magnitude. center at 25

// base-line 0 to darken and < 0 to auto hide (grep rephide)

out = parseInt(out);

return out;

};

```javascript

for (var i = 0; i < _accounts.length; i++) {

_accounts[i] = `${_accounts[i]} - ${repLog10(acc[i].reputation)}`;

}

document.getElementById('accList').innerHTML = _accounts.join('<br/>');
