# 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 prompt-guard.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Queries the Google OSV.dev database in real time for known CVEs and GHSA security advisories affecting a specified PyPI, npm, Go, or Rust crate package, returning active vulnerabilities and patched versions.

## 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 prompt-guard-agentdiet-dev-real-time-open-source-package-cve-ghsa-8c732189
```

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

## 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. It is ideal for pre-deployment security checks, CI/CD pipeline dependency audits, or ad-hoc CVE lookups where up-to-the-minute advisory data matters. Prefer it over static vulnerability databases when freshness of CVE and GHSA data is critical.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Invalid ecosystem prefix causes parsing error or no results
- OSV.dev upstream unavailable — service returns timeout or 503
- Malformed package identifier (missing colon separator) may return an error or unintended results
- Package with no known vulnerabilities returns an empty advisories list, which could be misread as an 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://prompt-guard.agentdiet.dev/v1/cargo-vuln-scan)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, severity ratings, affected version ranges, and available patched versions for the queried package, sourced live from Google OSV.dev.
