# 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 live OSV.dev vulnerability data for a given open-source package and returns active CVEs, GHSA advisories, and patched version information.

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-290a81e6
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates — specifically when you want both CVE and GHSA advisory coverage sourced directly from Google OSV.dev. Prefer this over static database lookups when freshness matters (e.g. pre-deployment checks, CI/CD pipelines, or evaluating new dependencies).

## Known failure modes

- Package not found in the specified ecosystem returns an empty or null advisory list
- Malformed package identifier (missing ecosystem prefix) may result in ambiguous or failed lookup
- OSV.dev upstream unavailability may cause timeout or degraded response
- Unknown ecosystem identifiers return an error
- Rate limits or payment failures result in HTTP 402 or 429 responses

## 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/cve-lookup)

## Output

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