Api Fuzzing Bug Bounty
This is a comprehensive reference for offensive API testing during bug bounties and pentests. It covers REST, SOAP, and GraphQL with concrete techniques for finding IDORs, authentication bypasses, injection points, and rate limit issues. The GraphQL section is especially dense with introspection queries, batching attacks, and schema enumeration tricks. It includes actual payloads you can adapt, like IDOR bypass techniques using array wrapping and parameter pollution, plus endpoint bypass strings for 403 responses. The checklist format makes it easy to methodically work through common API vulnerabilities. If you're hunting bugs or doing authorized security assessments, this gives you a structured workflow with ready to use examples rather than theoretical descriptions.

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.
Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
- Ask the user to state the exact target URL, IP, account, or resource.
- Ask the user to confirm written authorization and the permitted scope.
- Show the exact command(s) and explain their expected effect.
- Wait for explicit confirmation in the current conversation.
Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.
AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.
