What problem does it solve?

This skill helps security researchers and developers identify API security weaknesses by guiding structured fuzz testing across REST, SOAP, and GraphQL endpoints, reducing blind spots and accelerating vulnerability discovery.

Core Features & Use Cases

  • API Reconnaissance and endpoint discovery across versioned APIs (e.g., /v1, /v2, /v3).
  • Fuzzing with customizable wordlists and payload strategies to reveal misconfigurations, weak auth, and data exposure.
  • Vulnerability coverage including IDOR, authentication bypass, SQLi, SSRF, XXE, and improper input validation for REST, GraphQL, and SOAP APIs.
  • Security assessment workflow support for bug bounty engagements, continuous hardening, and pre-release security testing.

Quick Start

Configure the fuzzer with your target API URL, wordlists, and endpoint scope, then run the workflow with the provided scripts. Example: python3 fuzz_api.py --target https://api.example.com --wordlist /path/to/wordlist.txt --endpoints /v1,/v2,/v3 --auth-token "YOUR_TOKEN" --output findings.json
