# 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 Google OSV.dev in real time to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust 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 prompt-guard-agentdiet-dev-real-time-open-source-package-cve-ghsa-0ffe923c
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev specifically for PyPI, npm, Go modules, or Rust crates. It is ideal for automated dependency audits, CI/CD security gates, or agent-driven supply chain checks where freshness matters. Prefer it over static NVD lookups when you need GHSA advisories in addition to CVEs, or when you want the authoritative open-source ecosystem vulnerability database without managing API keys.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Invalid ecosystem prefix causes parse error or unrecognized package
- OSV.dev upstream unavailable — request times out or returns 502/503
- Malformed package identifier (missing colon separator) may result in ambiguous ecosystem resolution
- Package exists but has no recorded vulnerabilities — empty advisories array returned

## 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/pypi-vuln-scan)

## Output

Returns a list of active vulnerabilities for the queried package, including CVE and GHSA identifiers, vulnerability descriptions, severity information, affected version ranges, and the earliest patched versions available — sourced live from Google OSV.dev.
