POST /scan/v1/code/scan

unprobed

Static security scan of a code snippet. Finds hardcoded secrets (AWS keys, private keys, API keys, DB connection strings with passwords), eval/exec, command injection, HTTP calls with no timeout, weak hashes (md5/sha1), bare except and unverified JWT. Returns one entry per finding with rule, severity, exact line number, the offending line and a suggested fix. Rule-based and deterministic: no LLM,…

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
