# 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 to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate packages.

## 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-caecbd78
```

Example prompt: Can you check the PyPI:requests package for any active CVEs or GHSA security advisories and tell me which versions have patches?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust (crates.io) packages, especially when you want CVE and GHSA advisory details with patched version information in a single call without running a local scanner.

## Known failure modes

- Invalid or unrecognized package name returns empty or error response
- Unsupported ecosystem prefix causes bad request
- Network or OSV.dev upstream downtime results in timeout or 5xx error
- Package with no known vulnerabilities returns empty advisories list
- Malformed ecosystem:name format may be rejected

## 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/pypi-vuln-scan)

## Output

Returns a structured list of active vulnerabilities for the queried package, including CVE and GHSA identifiers, affected version ranges, severity ratings, and the patched versions that resolve each issue, sourced live from Google OSV.dev.
