grapix 0.1.1

An automated GraphQL/API endpoint extractor using Playwright.

grAPI — Live API Discovery Tool

grAPI is a simple but powerful utility for pentesters and security researchers who need to discover API endpoints on websites by interacting with them in real time. It uses Playwright under the hood to launch a real browser so you can explore the target and see API calls pop up in your terminal as they happen.

---

What It Does

This tool:

• Opens your target URL in a real browser so you can click around just like a user.
• Captures any API endpoints the page hits via XHR, Fetch or other network calls.
• Scans loaded JavaScript files for hidden or hardcoded API paths.
• Gives you color coded output instantly so you don’t have to wait.
• Lets you save the endpoints in a simple txt or json file.
• Generates a Postman collection for easy import into Postman or Burp.

Why It’s Useful

Unlike traditional scanners that only look at source code, grAPI listens to actual traffic as you use the page. That means it catches dynamic APIs that appear after a click, form submit or other interaction.

And because you do the browsing yourself, you control exactly which parts of the app you want to explore. The output is kept clean and minimal so you can jump straight into testing.

Installation

Make sure you have Python 3.10+ installed.

You can install grAPI using pip:

# Install grapi
pip install grapix

# Install Playwright browser binaries
playwright install

Or from source

git clone https://github.com/DghostNinja/grAPI.git
cd grAPI

# Install grapi
pip install .

# Install Playwright browser binaries
playwright install

• OPTIONAL: Add this line to your shell config (~/.bashrc, ~/.zshrc, or ~/.profile depending on your shell):

export PATH="$HOME/.local/bin:$PATH"
source ~/.bashrc   # or source ~/.zshrc

---

Usage

Here’s a typical example:

python3 grAPI.py --url https://targetsite.com -o apis.txt -p apis.postman.json

OR(Recommended):

grAPI --url https://targetsite.com -o apis.txt -p apis.postman.json

This will:

1. Launch the browser and open the target.
2. Print API endpoints as they happen — color coded by HTTP method.
3. Save them into a file (apis.txt) and a Postman collection (apis.postman.json).

When you’re done exploring the app, hit Enter in your terminal to stop the scan.

Optional Arguments

Argument	Description
--url	Target page URL
--timeout	Page load timeout in seconds. 0 disables timeout
--scroll	Automatically scrolls the page to trigger more API calls
-o	Output filename for saving endpoints (txt or json)
-p	Export captured endpoints as a Postman collection file

---

Example Output

[API detected] POST: http://crapi.apisec.ai/identity/api/auth/forget-password
[API detected] GET: http://crapi.apisec.ai/shop/api/products
[JS-detected] /user/profile/update-profile-picture/

After hitting Enter:

[+] Total API endpoints captured: 3
[+] Saved 3 endpoints to apis.txt
[+] Saved Postman collection to apis.postman.json
