Stack Facts Package Upgrade Safety Check
x402
Stack Facts Package Upgrade Safety Check is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-19).
Checks whether upgrading an npm or PyPI package from one version to another is safe, surfacing malware, OSV vulnerabilities, CISA KEV exploited CVEs, deprecation status, licence changes, and compatibility issues.

How this service works
Check a package before install: malware, known vulnerabilities (OSV), exploited CVEs (CISA KEV) and end-of-life, plus LLM prices; signed answers, pay per call in USDC, no account or API key.
Output
Returns a structured JSON object containing an overall upgrade verdict (safe/caution/review), security advisories broken down by introduced/fixed/still-open/unknown, CISA KEV CVE lists, deprecation and yanked flags, licence details and change detection, Node.js/Python version compatibility changes, and a list of reasons behind the decision — all signed and drawn from OSV, CISA KEV, and package registry data.
Example use cases
Dependency bump PR safety review
“We have a PR bumping 'axios' in npm from 1.3.0 to 1.7.2 — can you check if this upgrade is safe, including any open CVEs, exploited vulnerabilities, or licence changes I should know about?”
Python package vulnerability check
“Before I upgrade 'requests' on PyPI from 2.28.0 to 2.32.0 in our SaaS product, run a safety check and tell me if there are any advisories, CISA exploited CVEs, or deprecation warnings.”
Automated dependency policy enforcement
“Check whether upgrading the npm package 'lodash' from 4.17.20 to 4.17.21 is safe for internal use — I need to know about any introduced vulnerabilities, yanked status, and whether the licence is still MIT.”
Technical details
Endpoint
GEThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/upgrade/%7Becosystem%7D/%7Bname%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or CI/CD workflow needs to evaluate the safety of a specific package version upgrade before merging a dependency bump, and requires authoritative data from OSV, CISA KEV, and package registries in a single signed, pay-per-call response with no account setup. Prefer this over generic vulnerability scanners when you need a direct before/after comparison of two specific versions including licence drift and exploitation status.
Side effects
- Package name not found in the specified ecosystem — returns error or empty data
- Unsupported ecosystem (only npm and pypi are accepted) — schema validation failure
- Version strings not found in registry — may return stale or partial data
- Payment failure or insufficient USDC balance — 402 response blocking the call
- Network timeout to upstream data sources (OSV, CISA KEV) — may return stale flag
