# Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev)

> Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev) is a paid API for AI agents from onchain-risk.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev in real time to return active CVEs, GHSA advisories, and patched versions for a named PyPI, npm, Go, or Rust crate package.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability onchain-risk-agentdiet-dev-real-time-open-source-package-cve-ghsa-3f95e121
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories right now, and tell me what patched versions are available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust (crates.io) packages — especially when you want both CVE and GHSA advisory coverage in a single call with patched-version guidance. Prefer it over static NVD snapshots or GitHub Dependabot alerts when freshness and multi-ecosystem breadth matter.

## Known failure modes

- Package not found in OSV.dev returns empty advisory list or 404-equivalent
- Malformed ecosystem prefix (e.g. 'Pypi' vs 'PyPI') may yield no results
- Package with no known vulnerabilities returns empty CVE/GHSA arrays
- Rate limiting or OSV.dev upstream downtime may cause timeout or 503
- Missing required 'package' query parameter returns 400 validation error
- Payment not completed returns HTTP 402 payment required

## How this service works

Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and returns active CVEs, GHSA advisories, and patched versions. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/zero-day-advisories)

## Output

Returns a structured object containing active CVEs, GHSA advisory IDs, severity levels, affected version ranges, and the earliest patched version for the queried open-source package, sourced live from Google OSV.dev.
