# 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 mesh.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev for live CVE and GHSA vulnerability data for any PyPI, npm, Go, or Rust package and returns active advisories and patched versions.

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 mesh-agentdiet-dev-real-time-open-source-package-cve-ghsa-1e2ec94a
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories, and tell me which version I should upgrade to in order to be safe?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data sourced directly from Google OSV.dev for open-source packages across PyPI, npm, Go, or crates.io ecosystems. Prefer it over static NVD lookups when you need up-to-date GHSA advisories and patched version recommendations in a single call. Ideal for CI/CD security gates, dependency auditing agents, or pre-release supply chain checks where freshness of vulnerability data matters.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or error if ecosystem/name is invalid
- Malformed package identifier (missing ecosystem prefix) may result in ambiguous or failed lookup
- OSV.dev upstream API unavailability causes timeout or 5xx error
- Rate limiting or payment failure ($0.01/call via x402) blocks the request
- Package with no known vulnerabilities returns empty advisories list, which may be misread as an error

## 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://mesh.agentdiet.dev/v1/maven-vuln-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, affected version ranges, severity ratings, and recommended patched versions for the queried package from the live OSV.dev database.
