# 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 hn-pulse.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev in real time to retrieve active CVE and GHSA advisories, severity scores, and patched versions for a given PyPI, npm, Go, or Rust package.

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 hn-pulse-agentdiet-dev-real-time-open-source-package-cve-ghsa-20b3f2e2
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories and tell me which versions are patched?

## When to prefer this

Choose this endpoint when you need real-time, up-to-date vulnerability intelligence from OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems — particularly when you need CVE and GHSA advisories with patched version data in a single call, without maintaining your own vulnerability database.

## Known failure modes

- Package not found in OSV.dev database — returns empty or error response
- Malformed ecosystem:name format causes a 400 bad request
- No vulnerabilities found returns an empty advisories list (not an error)
- Rate limit or upstream OSV.dev unavailability may cause a 503 or timeout
- Payment required (HTTP 402) if USDC micropayment not attached

## 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://hn-pulse.agentdiet.dev/v1/osv-cve-vulnerability-radar)

## Output

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