# 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 to return active CVEs, GHSA advisories, and patched versions for a given 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-5a37221d
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories right now, and tell me which versions have patches available?

## When to prefer this

Choose this endpoint when you need live, up-to-date vulnerability intelligence from Google OSV.dev for open source packages across PyPI, npm, Go, or Rust ecosystems — especially when you need both CVE and GHSA advisory coverage in a single call. Prefer this over static SBOMs or local databases when you need real-time data, and over GitHub's dependency graph when you need multi-ecosystem support including Rust crates.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-equivalent
- Invalid package identifier format — error indicating expected 'Ecosystem:name' format
- OSV.dev upstream timeout or unavailability — returns error or degraded response
- Unrecognized ecosystem prefix — only PyPI, npm, Go, crates.io are supported
- Payment not completed (HTTP 402) — endpoint requires $0.01 USDC per call via x402

## 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/cargo-vuln-scan)

## Output

Returns a structured list of active vulnerabilities for the queried package, including CVE identifiers, GHSA advisory IDs, severity details, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
