# API Fuzzer
## Overview
Perform API fuzzing to discover crashes, unhandled exceptions, security vulnerabilities, and edge case failures by sending malformed, unexpected, and boundary-value inputs to API endpoints. Supports RESTler (stateful REST API fuzzing), Schemathesis (OpenAPI-driven property-based testing), custom fuzz harnesses with fast-check, and OWASP ZAP active scanning.
## Prerequisites
- API specification available (OpenAPI/Swagger, GraphQL SDL, or Protobuf definitions)
- Target API running in a test environment (never fuzz production)
- Fuzzing tool installed (Schemathesis, RESTler, or custom harness with fast-check/Hypothesis)
- API authentication credentials for protected endpoints
- Error logging enabled on the target server to capture crashes and stack traces
