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

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for any PyPI, npm, Go, or Rust crate 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 defi-yield-agentdiet-dev-real-time-open-source-package-cve-ghsa-90d35668
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for a specific open source package across PyPI, npm, Go modules, or Rust crates — especially when you want both CVE and GHSA advisory data with patched version recommendations in a single call, without maintaining your own vulnerability database.

## Known failure modes

- Package not found in OSV.dev — returns empty or null vulnerability list
- Invalid ecosystem prefix causes query failure or empty results
- OSV.dev upstream unavailability leads to timeout or error response
- Malformed package identifier (missing ecosystem prefix) may yield no results
- Payment failure via x402 prevents endpoint access

## 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://defi-yield.agentdiet.dev/v1/epss-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, severity ratings, affected version ranges, and the versions in which vulnerabilities have been patched, sourced live from Google OSV.dev.
