What does API Discovery & Inspector help with?

API Discovery & Inspector helps with a focused security or privacy workflow such as inspection, validation, encoding, reporting, or defensive analysis.

Who can use API Discovery & Inspector?

Security learners, developers, sysadmins, website owners, DevOps teams, and privacy-conscious users can use it for quick browser-based checks.

Does API Discovery & Inspector replace a professional security review?

No. It is a practical helper for education and first-pass checks. High-risk systems should still be reviewed with proper testing, monitoring, and expert validation.

AI Reconnaissance Insights

Understanding API Reconnaissance

API Discovery and Information Gathering (Reconnaissance) is the cornerstone of modern web security auditing. In today's decentralized web, applications are no longer monolithic entities; they are composite structures relying on multiple internal and external API endpoints. Our API Discovery & Inspector is designed to proactively find these interaction points by analyzing client-side manifests, JavaScript bundles, and environmental footprints.

Passive Extraction

We analyze public HTML attributes, <script> tags, and source maps to identify hardcoded strings that match API path signatures like `/api/v1/` or `graphql`.

Heuristic Mapping

By probing common paths like `/swagger.json` or `/.env`, the tool reconstructs the likely architecture of the backend without invasive scanning.

Why Use an API Inspector?

Security professionals and developers use API inspectors to visualize the "attack surface" of a website. A hidden, unauthenticated endpoint can be a gateway to sensitive data exposure. By identifying these endpoints early, developers can implement proper CORS policies, JWT validation, and rate limiting.

Ethical Use Only

This tool is intended for authorized security research, educational purposes, and internal development testing. Unauthorized reconnaissance against systems you do not own or have permission to test may be illegal in your jurisdiction.

Step-by-Step Security Audit

Perform a thorough API audit using these simple steps:

Target Input: Enter the full URL of the application you wish to inspect.
Select Modules: Enable "JS Bundles" for deep script scanning and "Public Docs" to find hidden Swagger manifests.
Evaluate Risk: Review the results table. Items marked with High Risk (like `/admin` or `/config`) should be prioritized for access control checks.
Export Report: Use the JSON export feature to document your findings for your security team or for inclusion in a bug bounty report.

Frequently Asked Questions

What is Swagger/OpenAPI Probing?

Swagger is a standard for documenting REST APIs. Many developers accidentally leave the documentation UI or JSON manifest public. Our tool probes standard paths to find these, which can reveal every single function of an API.

Is this tool safe for my website?

Yes. The tool performs standard HTTP requests (via a proxy to bypass CORS) just like a normal browser. It does not perform "fuzzing" or aggressive brute-force attacks that could affect server stability.

Why analyze JavaScript bundles?

Modern frameworks like React and Vue bundle their API interaction logic into Large JS files. By searching these files for URL patterns, we can find endpoints that aren't visible in the initial HTML page source.

Privacy Fact: This scan is performed using our secure proxy infrastructure. Your personal IP address is never directly exposed to the target server during the reconnaissance phase.
