# 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 mcp-compiler.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-28).

Queries live OSV.dev vulnerability data for a named package (PyPI, npm, Go, Rust) and returns active CVEs, GHSA advisories, and patched versions.

## Facts

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 mcp-compiler-agentdiet-dev-real-time-open-source-package-cve-ghsa-4ea5873e -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need real-time, live vulnerability data from Google OSV.dev for a specific open-source package across PyPI, npm, Go, or Rust ecosystems — especially when you need CVE IDs, GHSA advisory numbers, and patched version recommendations in a single call without managing OSV.dev API credentials yourself.

## Known failure modes

- Package identifier not found in OSV.dev — returns empty or 404-like response
- Invalid ecosystem prefix causes lookup failure
- Network timeout reaching OSV.dev upstream — service may return error
- Payment not fulfilled (HTTP 402) — endpoint requires $0.01 USDC per call
- Malformed package string (missing ecosystem or empty name) — rejected by input validation

## 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://mcp-compiler.agentdiet.dev/v1/go-module-cve)

## Output

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