Raxis API Tool

The Raxis API tool is a simple Node.js class built for assessing API endpoints. The class is designed to be fully extensible and modifiable to support many different types of JSON-based REST APIs. It automatically handles token-based authentication, proxies requests, and exposes several functions designed to make it easier and faster to write a wrapper around an API and associated test code for the purposes of a penetration test.

This tool is not designed to work on its own, but to serve as a building block and quickstart for code-based API penetration testing.

Getting Started

These instructions will help you get set up to start building off the tool to assess an API.


You'll need a few things in order to start building off of the Raxis API Tool:

  • A working knowledge of ES6 JavaScript.
  • A REST API and associated documentation.
  • Node.js 8.x.x installed on your machine (


For most use cases, you can simply download or clone this repository and enter into the /test directory, and create a new test file to start coding.

git clone
cd api-tool/tests
touch my-api.js

Configuration Files

You can specify your API configuration in a .json file and require it in your test code, or you can use a JavaScript object. Configuration files can be stored in the api-tool/config directory for cleanliness. Here's an example configuration file:

  "host": "",
  "username": "admin",
  "password": "password",

  "proxy": null,
  "endpoints": {
    "token": "/this/endpoint/is/required",
    "anotherEndpoint": "/specify/other/endpoints/here/",

Configuration files can be included in your test JavaScript file like this:

const myApiConfig = require('../config/my-api.json');

To use a configuration file, simply pass it as the first parameter in the constructor of your extended APITool class:

const myAPI = new MyAPI(myApiConfig);

Writing Tests

To write tests, require and extend the base APITool class. Use ES6 syntax, supported by Node 8.x.x, to do this. Once the class is extended, add methods to correspond to each of the API methods you wish to test. You can access the endpoints defined in the configuration file as shown below, which is great in the event that they should change.

const APITool = require('../lib/api-tool');
const myAPIConfig = require('../config/my-api.json');

class MyAPI extends APITool {
    deleteUser(id) {
        // Note: this will return a promise. Use the async/await functions to have the easiest time with these.
        return this.doDelete(`${this.endpoints.user}/${id}`, APITool.Auth.Token);

const api = new MyAPI(myAPIConfig);

Example Code

See test/example.js for an example of how to extend the APITool class and write tests.


Raxis does not provide assistance with APITool. It's yours to use and do with as you please, but we can't help you if something goes wrong. Raxis does not condone unauthorized or illegal testing by releasing this code, and is not liable for any parties that chose to do so.
