# 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 serp-extract.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).

Queries Google OSV.dev for live CVE and GHSA vulnerability advisories for a given PyPI, npm, Go, or Rust crate package and returns active vulnerabilities with patched versions.

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 serp-extract-agentdiet-dev-real-time-open-source-package-cve-ghsa-a3fca734 -d '<json body>'
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and tell me which versions have patches?

## When to prefer this

Use this endpoint when you need real-time, live vulnerability data from Google OSV.dev for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. Prefer it over static NVD database lookups when you need the freshest CVE and GHSA advisory data, including very recent disclosures that may not yet appear in cached sources.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or error
- Invalid ecosystem prefix causes parsing error
- OSV.dev upstream timeout results in service error
- Malformed package identifier (missing ecosystem) leads to validation error
- Package has no known vulnerabilities — returns empty result set

## 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://serp-extract.agentdiet.dev/v1/zero-day-advisories)

## Output

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