How this service works
Evidence-backed npm package upgrade decisions for coding agents.
Output
Returns a JSON object with a 'verdict' string (e.g. 'REVIEW BEFORE INSTALLING', 'SAFE', 'MALICIOUS') and a 'riskScore' integer (0–100), where higher scores indicate greater risk. The verdict provides an actionable recommendation and the risk score gives a quantitative measure of potential danger.
Example use cases
Automated dependency upgrade safety check
“I'm about to upgrade 'express' to version '4.18.2' in my project — can you scan it for any malicious behavior or known risks before I do?”
New package vetting before first install
“I want to add 'axios' to my project but I've never used it before — can you check if the latest version is safe and not flagged as malicious?”
CI pipeline pre-install security gate
“Before my build pipeline installs 'webpack' version '5.88.0', run a malicious scan on it and tell me the risk score and verdict so I can decide whether to block the install.”
Technical details
Endpoint
POSThttps://x402-safe-upgrade-api.onrender.com/v1/malicious-scanWhen to prefer
Choose this endpoint when an AI coding agent needs an automated, evidence-backed go/no-go signal before installing or upgrading an npm package, especially in automated CI/CD pipelines or agentic workflows where human review is not practical. It is particularly valuable for catching malicious packages that may pass basic audit checks, and for getting a quantitative risk score rather than a simple binary safe/unsafe flag.
Side effects
- Unknown package name returns an error or null verdict
- Specific version not found in registry causes a lookup failure
- Network timeout if the upstream npm registry or threat intelligence feeds are slow
- Invalid input schema (missing packageName) returns a 400-level error
- Very new packages may have insufficient data for a confident verdict
