# 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 for live CVE and GHSA vulnerability advisories for a given PyPI, npm, Go, or Rust crate package and returns active vulnerabilities with patched versions.

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-6db40ab3
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me which version I should upgrade to in order to be safe?

## When to prefer this

Choose this endpoint when you need live, real-time vulnerability data from Google OSV.dev for PyPI, npm, Go modules, or Rust crates — especially when you want CVE and GHSA advisories in a single call without setting up your own OSV API integration. It is ideal for agent-driven CI/CD security gates, dependency auditing workflows, or on-demand package safety checks where freshness matters.

## Known failure modes

- Unknown or misspelled package name returns empty or error response
- Unsupported ecosystem prefix causes validation error
- Package with no known vulnerabilities returns empty advisories list
- OSV.dev upstream API downtime may cause timeout or error
- Malformed 'Ecosystem:name' format triggers input validation failure

## 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/maven-vuln-scanner)

## Output

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