# 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, $0.01/call, status unknown (last checked 2026-10-23).

Queries Google OSV.dev in real time for a given package and returns active CVEs, GHSA advisories, and patched version information.

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-5b8e2ad2 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need real-time, up-to-date CVE and GHSA vulnerability data for open source packages across PyPI, npm, Go, or Rust ecosystems sourced directly from Google OSV.dev. Prefer it over static databases or periodic audit tools when freshness matters or when scanning individual dependencies during CI/CD, code review, or agent-driven security workflows.

## Known failure modes

- Invalid or unrecognized package identifier returns an error or empty result
- Ecosystem prefix missing or malformed (e.g. 'PyPI:' vs 'pypi:') may cause lookup failure
- Package with no known vulnerabilities returns an empty advisories list (not an error)
- Network or OSV.dev upstream unavailability causes a 5xx or timeout response
- Rate limiting or payment failure (402) if x402 payment is not provided

## 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/ghsa-advisories)

## 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 patched/fixed versions sourced live from Google OSV.dev.
