How this service works
Evidence-backed npm package upgrade decisions for coding agents.
Output
Returns a JSON object with a `decision` block containing the version change type (major, minor, or patch) and a textual recommendation (e.g. 'REVIEW BEFORE UPGRADING' or 'SAFE TO UPGRADE'), plus an `evidence` block listing any known vulnerabilities found in the current and target versions of the package.
Example use cases
Automated dependency update safety check
“My CI pipeline wants to auto-merge a Dependabot PR bumping axios from 0.21.1 to 1.4.0. Can you check whether that upgrade is safe — specifically any vulnerabilities in either version and whether the version jump is major?”
Security audit before production deploy
“We're about to ship to production and I need to know if upgrading express from 4.17.1 to 4.18.2 introduces or fixes any known CVEs. Give me a recommendation.”
Coding agent pre-upgrade validation
“Before you apply that package.json change, check if it's safe to go from minimist 1.2.5 to 1.2.8 — look for vulnerabilities in both versions and tell me if I should review it carefully first.”
Technical details
Endpoint
POSThttps://x402-safe-upgrade-api.onrender.com/v1/upgrade-decisionWhen to prefer
Choose this endpoint when an AI coding agent needs an automated, evidence-backed go/no-go decision before bumping an npm dependency — especially for major version upgrades or in CI pipelines where human review is limited. It is preferable over manual npm audit or raw CVE database lookups when you want a single structured recommendation with vulnerability evidence bundled together.
Side effects
- Unknown or misspelled package name returns an error or empty evidence
- Invalid semver strings for fromVersion or toVersion cause a validation error
- Package exists on npm but vulnerability data is unavailable, resulting in empty evidence arrays
- Service may be slow or unavailable due to hosting on a free-tier Render instance
- Payment required (402) if x402 payment header is not included
