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

Queries Google OSV.dev for live CVE and GHSA vulnerability advisories for a given PyPI, npm, Go, or Rust crate package, returning active vulnerabilities and patched versions.

## Facts

- Price: $0.01/call
- Payment: MPP
- Status: unknown
- Last checked: 2026-10-21

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 agentdiet-dev-real-time-open-source-package-cve-ghsa-vulnerability-4f9f77b3
```

Example prompt: Can you check whether the PyPI package 'requests' has any active CVEs or GHSA advisories, and let me know if there's a patched version available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev specifically for PyPI, npm, Go, or Rust crate packages. It is ideal for automated dependency auditing pipelines, pre-deployment security checks, or CI/CD integration where up-to-date CVE and GHSA data matters. Prefer it over static databases when currency of vulnerability data is critical.

## Known failure modes

- Package not found in any supported ecosystem — returns empty or error response
- Invalid ecosystem prefix causes malformed query — no results returned
- OSV.dev upstream unavailable — service may timeout or return 502
- Package name typo returns no vulnerability data without indication of error
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not completed

## 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://agentdiet.dev/v1/cve)

## Output

Returns a structured list of active vulnerability records for the queried package, including CVE IDs, GHSA advisory identifiers, vulnerability descriptions, affected version ranges, and available patched versions sourced live from Google OSV.dev.
