How this service works
ShieldAPI - x402 security preflight before agents install or run npm/PyPI dependencies
Output
Returns a JSON object with a numeric safety score (0-100), a status string ('ALLOW' or 'BLOCK'), and an array of flags indicating any detected supply chain risks or malicious indicators for the specified package.
Example use cases
Validate dependencies before CI/CD deployment
“Before we deploy this build, scan all the npm packages in our package.json and let me know which ones have supply chain risks — I need to know the safety scores and which ones we should block.”
Vet Python packages for open source projects
“I'm about to add a new PyPI package called requests-html to our data pipeline — can you check if it's safe to use and give me the risk assessment?”
Quick malware check for suggested packages
“My teammate recommended we use the npm package axios for HTTP requests — run a supply chain security check on the latest version and tell me if there are any red flags or malicious indicators.”
Technical details
Endpoint
GEThttps://shield.vainplex.dev/api/cdp/check/packageWhen to prefer
Use this endpoint when you need a fast, automated pre-flight safety check on a specific package before installing or deploying it in a software project, especially in CI/CD pipelines or agentic workflows where dependency vetting is required. Prefer this over generic vulnerability scanners when you need a binary ALLOW/BLOCK decision with a risk score for npm, pypi, or other ecosystems.
Side effects
- Unknown or unrecognized ecosystem returns an error
- Package not found in the ecosystem registry
- Missing required query parameters (ecosystem, name, version) returns a 400 error
- Payment failure via x402 protocol results in 402 response
- Network timeout for unknown or newly published packages
