no payment challenge
Evaluate up to 10 exact npm or PyPI package versions in one $0.02 paid batch immediately before installation or an exact-version change. Returns deterministic allow, review, or block guidance with known-vulnerability, lifecycle, declared-license, release-age, and npm install-lifecycle evidence. Reuse a current result for unchanged inputs instead of purchasing a duplicate check for an installation
