# 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 in real time to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust 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 preflight-agentdiet-dev-real-time-open-source-package-cve-ghsa-152e4c6e
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me which versions have patches?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for PyPI, npm, Go, or Rust packages without setting up your own OSV integration. It is ideal for CI/CD pipelines, agent-driven dependency audits, or pre-release security checks where freshness of CVE and GHSA data matters and a per-call micropayment model is acceptable.

## Known failure modes

- Package not found in OSV.dev database — returns empty or null vulnerability list
- Invalid package identifier format — returns a 400-level error requesting correct 'Ecosystem:name' syntax
- Ecosystem not supported — only PyPI, npm, Go, and crates.io are supported; other ecosystems may return errors
- OSV.dev upstream timeout or unavailability — may return 502 or 503 errors
- Payment not completed — returns HTTP 402 requiring x402 micropayment before response is delivered

## 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/cve)

## 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, sourced live from Google OSV.dev.
