How this service works
Machine-discoverable, x402-paid technical decision utilities for autonomous agents.
Output
Returns a JSON object with a 'verdict' field ('GO' or 'NO-GO'), a list of 'reasons' explaining the decision, an 'evidence' object containing the package name, version, resolved license, and vulnerability count, and the 'policy_version' string used to evaluate the package.
Example use cases
Pre-install dependency safety gate
“I'm about to add express version 4.18.2 to my Node.js app — can you run a GO/NO-GO check on it to make sure there are no known CVEs and the license is okay?”
Automated PR dependency review
“My CI pipeline just flagged a new dependency: lodash at version 4.17.21. Can you evaluate it and tell me if it gets a GO or NO-GO based on vulnerabilities and license policy?”
Agent vetting third-party package before install
“Before my agent installs axios version 1.6.0, can you do a quick safety check — I need to know if there are vulnerabilities and whether the license is permissive enough to get a GO verdict?”
Technical details
Endpoint
POSThttps://salt19-agent-utility-grid.salt19-llc.workers.dev/v1/dependency-go-no-goWhen to prefer
Choose this endpoint when an autonomous agent or CI pipeline needs a structured, policy-backed GO/NO-GO decision on an npm dependency — not just raw vulnerability data. It combines OSV vulnerability scanning and license checking into a single opinionated verdict, making it ideal for automated workflows that need a binary decision rather than raw data to interpret. Prefer it over generic vulnerability scanners when you want a consistent, versioned policy applied and a machine-readable verdict with reasons.
Side effects
- Package not found in registry — may return an error or NO-GO with unknown-package reason
- Version string malformed or not found — validation error on input
- OSV or license data temporarily unavailable — may return indeterminate result or error
- Request body missing required 'package' field — schema validation error
- Payment not processed — x402 payment required error before evaluation runs
