# 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 return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate 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-610055b3
```

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

## When to prefer this

Choose this endpoint when you need live, authoritative vulnerability data directly from Google OSV.dev for PyPI, npm, Go, or crates.io packages. It is ideal for pre-deployment audits, CI/CD security gates, or ad-hoc dependency checks where up-to-date CVE and GHSA advisory data is critical. Prefer it over static SCA tools when you need real-time intelligence rather than a snapshot database.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if ecosystem/name is invalid
- Malformed package identifier (missing ecosystem prefix) may return no results
- OSV.dev upstream unavailability may cause timeouts or 5xx errors
- Packages with no known vulnerabilities return an empty advisory list, which may be misread as an error
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed

## 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/epss-scanner)

## Output

Returns a structured list of active CVEs and GHSA security advisories affecting the queried package, including vulnerability IDs, severity details, affected version ranges, and the earliest patched/safe version available.
