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

Queries Google OSV.dev live vulnerability data for a given PyPI, npm, Go, or Rust 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 alpha-stream-agentdiet-dev-real-time-open-source-package-cve-ghsa-9e4f9f89
```

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 CVE and GHSA vulnerability data for a specific open-source package across PyPI, npm, Go, or Rust ecosystems — especially when you need the most current advisory intelligence directly from OSV.dev rather than a static or cached database. Prefer it for automated security checks in CI/CD pipelines, agent-driven dependency audits, or pre-deployment risk assessments.

## Known failure modes

- Package not found or unrecognized ecosystem prefix returns empty results or error
- Malformed package identifier (missing ecosystem or typo) may return no results
- OSV.dev upstream unavailability could cause timeout or partial data
- Payment failure (HTTP 402) if x402 micropayment is not completed
- Rate limiting or quota exhaustion on the upstream OSV.dev API

## 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://alpha-stream.agentdiet.dev/v1/zero-day-advisories)

## Output

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