APIFuzz

Fuzz test API endpoints with intelligent payload generation

Code & DevelopmentPaid

APIFuzz reads OpenAPI specifications and generates intelligent fuzz test payloads for each endpoint, testing boundary conditions, type coercion vulnerabilities, injection vectors, and malformed input handling. The tool goes beyond random mutation by understanding API semantics to generate payloads that are structurally valid but semantically adversarial, catching bugs that simple random fuzzing misses. Security teams use it during penetration testing engagements while API developers use it in CI pipelines to catch input validation gaps before deployment.
