# 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 llms-generator.agentdiet.dev, paid per call via MPP, $0.01/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 PyPI, npm, Go, or Rust crate packages.

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 llms-generator-agentdiet-dev-real-time-open-source-package-cve-ghsa-b133b7cc
```

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 latest patched version is?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems, sourced directly from Google OSV.dev. It is ideal for CI/CD pipelines, pre-deployment security audits, or agent-driven dependency checks where freshness matters. Prefer this over static databases or periodic snapshot tools when you need up-to-the-minute CVE and GHSA advisory accuracy.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style error
- Invalid ecosystem prefix or malformed package identifier — returns validation error
- OSV.dev upstream timeout or unavailability — returns 503 or gateway error
- Package exists but has no known vulnerabilities — returns empty advisories array
- Payment not completed (HTTP 402) — request blocked until x402 payment is fulfilled

## 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://llms-generator.agentdiet.dev/v1/epss-scanner)

## Output

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