# 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 alpha-stream.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 a given PyPI, npm, Go, or Rust package.

## 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 alpha-stream-agentdiet-dev-real-time-open-source-package-cve-ghsa-4bf99a02
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me which version has the fixes?

## When to prefer this

Choose this endpoint when you need real-time, authoritative CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems. It is ideal for CI/CD security gates, pre-deployment dependency audits, and supply chain risk checks where up-to-date OSV.dev intelligence is required. Prefer it over static vulnerability databases when freshness matters.

## Known failure modes

- Unknown or misspelled package name returns empty or error response
- Unsupported ecosystem (e.g. Maven, NuGet) not recognized by OSV.dev integration
- Rate limiting or OSV.dev upstream downtime causes delayed or failed response
- Package with no known vulnerabilities returns empty advisory list, which may be misinterpreted as an error
- Ambiguous package name without ecosystem prefix may return incorrect results

## 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://alpha-stream.agentdiet.dev/v1/maven-vuln-scanner)

## Output

Returns a structured object containing any active CVE identifiers, GHSA advisory references, vulnerability descriptions, severity information, and the package versions in which the vulnerabilities were patched, sourced live from Google OSV.dev.
