# 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 live intelligence for a given package and returns active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate ecosystems.

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-3bfea8f5
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me what the patched version is?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data sourced directly from Google OSV.dev for PyPI, npm, Go, or Rust crate packages. It is preferable over static databases when you need up-to-date CVE/GHSA advisories rather than cached snapshots, and when the target package ecosystem matches PyPI, npm, Go modules, or crates.io.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if ecosystem/name is invalid
- Malformed package identifier (missing ecosystem prefix) may return no results
- OSV.dev upstream unavailability causes timeout or degraded response
- Rate limiting or payment failure ($0.015/call via x402) results in 402 response
- Unknown ecosystem identifiers are rejected with a validation 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/vuln-scanner)

## Output

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