# 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 for live CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate packages.

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-c2e76215
```

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

## When to prefer this

Choose this endpoint when you need real-time, up-to-date CVE and GHSA vulnerability data for open source packages across PyPI, npm, Go, and Rust ecosystems via OSV.dev. Prefer it over static NVD snapshots or GitHub advisory RSS feeds when you need live data with patched version guidance in a single API call. Especially useful in automated CI/CD agents or supply chain security workflows that need programmatic, pay-per-call access without API key provisioning.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Invalid ecosystem prefix causes parsing error
- No vulnerabilities found for a package (not an error, but could be misread as failure)
- Payment required (HTTP 402) if x402 micropayment header is not included
- Upstream OSV.dev API unavailability causes timeout or 503

## 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/npm-vuln-scan)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory references, affected version ranges, and available patched versions for the queried package, sourced live from Google OSV.dev.
