# 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 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-cc44c873
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me which version I should upgrade to if there are known vulnerabilities?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for a specific open-source package across PyPI, npm, Go modules, or Rust crates. Prefer it over static NVD mirrors or offline databases when freshness matters — especially for CI/CD pipelines, pre-deployment audits, or agent-driven dependency triage where up-to-date CVE and GHSA coverage is critical.

## Known failure modes

- Unknown or misspelled package name returns empty results or 404
- Invalid ecosystem prefix causes a bad request error
- OSV.dev upstream unavailability results in a gateway or timeout error
- Package exists but has no known vulnerabilities returns an empty advisory list
- Ambiguous package name without ecosystem prefix may resolve incorrectly

## 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/zero-day-advisories)

## Output

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