# 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 PyPI, npm, Go, or Rust crate packages.

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-80b72559
```

Example prompt: Check the PyPI requests package for any active CVEs or GHSA security advisories and tell me if there are patched versions available.

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates, sourced directly from Google OSV.dev. Prefer it over static vulnerability databases when you need the most current CVE and GHSA advisories including patch status. Ideal for pre-dependency-addition checks, CI/CD security gates, and automated audits without needing to run local tooling like pip-audit or npm audit.

## Known failure modes

- Package not found in OSV.dev — returns empty or error response
- Invalid ecosystem prefix causes malformed request
- No vulnerabilities found may return empty advisory list (not an error)
- Upstream OSV.dev API unavailability causes request failure
- Malformed package identifier format results in bad request error

## 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/pypi-vuln-scan)

## Output

Returns a structured object listing active CVE identifiers, GHSA advisory IDs, severity information, affected versions, and patched/fixed versions for the requested package from the Google OSV.dev database.
