# 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 live vulnerability data for a given open-source package and returns active CVEs, GHSA advisories, and patched versions.

## 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-51fcf624
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data directly from Google OSV.dev for PyPI, npm, Go, or Rust (crates.io) packages, especially when you want CVE IDs and GHSA advisories together with patched version information in a single call. Prefer this over static NVD snapshots or offline databases when currency of data matters.

## Known failure modes

- Unknown or misspelled package name returns empty results or an error
- Unsupported ecosystem prefix causes a validation error
- OSV.dev upstream API downtime may result in timeout or error response
- Package with no known vulnerabilities returns an empty advisories list
- Malformed 'Ecosystem:name' format may return a parsing error

## 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/cve)

## Output

Returns a list of known vulnerabilities for the specified package, including CVE IDs, GHSA advisory identifiers, severity ratings, affected version ranges, and the earliest patched version available, sourced live from Google OSV.dev.
