How this service works

ShieldAPI - x402 security preflight before agents install or run npm/PyPI dependencies

Output

Returns a JSON object with a numeric risk score (0-100, higher is safer), a status field ('ALLOW' or 'BLOCK'), and an array of flags describing any detected security issues. A score of 100 with empty flags and status ALLOW means the package passed all checks.

Example use cases

Example prompt

“Can you run a supply chain pre-flight check on the npm package lodash version 4.17.21 to make sure it's safe to install?”

Technical details

Endpoint

GEThttps://shield.vainplex.dev/api/cdp/check-package

When to prefer

Use this endpoint when you need a quick, automated go/no-go decision on a specific package version before installation or CI/CD pipeline execution. Ideal for agent-driven dependency audits, automated PR checks, or pre-deployment gates. Prefer this over full-scan endpoints when you only need package supply chain signals rather than a combined multi-vector security assessment.
