# 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 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-16288e1f
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google's OSV.dev for open source packages in PyPI, npm, Go modules, or Rust crates. It is ideal for automated dependency audits, CI/CD security gates, or agent-driven supply chain checks where up-to-date CVE and GHSA data matters. Prefer it over static NVD lookups when you need patched version guidance alongside advisory details in a single call.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Malformed package identifier (missing ecosystem prefix) may cause lookup failure
- OSV.dev upstream unavailability may cause timeout or error response
- Unrecognized ecosystem prefix returns an error or empty result
- Rate limiting or payment failure (HTTP 402) if usage quota exceeded

## 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/osv-cve-vulnerability-radar)

## Output

Returns a structured list of active vulnerabilities for the queried package, including CVE IDs, GHSA advisory identifiers, severity levels, affected version ranges, and the earliest patched/fixed versions available from the OSV.dev database.
