# 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 whale-momentum.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev for live CVE and GHSA vulnerability advisories for a named PyPI, npm, Go, or Rust package and returns active vulnerabilities and 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 whale-momentum-agentdiet-dev-real-time-open-source-package-cve-ghsa-8d22d372
```

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 are patched?

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA vulnerability data sourced directly from Google OSV.dev for PyPI, npm, Go, or Rust packages. It is preferable over static NVD database lookups when you need up-to-date zero-day and recent advisory coverage. Ideal for automated dependency scanning, CI/CD security gates, or agent workflows that need to verify package safety before use.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Invalid ecosystem prefix causes query failure — ensure format is 'Ecosystem:name' (e.g. 'PyPI:requests')
- OSV.dev upstream API unavailable — service may return a 503 or timeout
- Unsupported ecosystem provided (e.g. Maven, NuGet) — results may be incomplete or absent
- Payment not completed (HTTP 402) — call blocked until x402 micropayment is fulfilled

## 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://whale-momentum.agentdiet.dev/v1/zero-day-advisories)

## Output

A structured object containing all active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, severity ratings, affected version ranges, and recommended patched versions for the queried package as sourced from Google OSV.dev.
