# 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 preflight.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev for live CVE and GHSA vulnerability advisories affecting a named PyPI, npm, Go, or Rust crate package, returning active vulnerabilities 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 preflight-agentdiet-dev-real-time-open-source-package-cve-ghsa-8dfb8134
```

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 been patched?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. It is ideal for automated dependency auditing, CI/CD security gates, or pre-deployment checks where freshness matters. Prefer this over static NVD snapshots when you need current GHSA advisories and patched version guidance without running a local scanner.

## Known failure modes

- Package not found in OSV.dev — returns empty or null advisory list
- Invalid ecosystem prefix causes parsing error
- Unrecognized package format returns validation error
- OSV.dev upstream unavailable causes timeout or 502
- No vulnerabilities found for a package returns empty results (not 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://preflight.agentdiet.dev/v1/maven-vuln-scanner)

## Output

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