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

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate packages in real time.

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 workflows-agentdiet-dev-real-time-open-source-package-cve-ghsa-4424129e
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories, and tell me which version fixes them?

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA vulnerability data directly from Google OSV.dev for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is preferred over static vulnerability databases or periodic batch scans when freshness matters — e.g. in CI/CD pipelines, pre-release audits, or agent-driven dependency reviews. It is not suitable for proprietary or closed-source software, or for ecosystems beyond those four supported ones.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result for obscure or misspelled packages
- Unsupported ecosystem — packages outside PyPI, npm, Go, and crates.io may not return meaningful results
- Ambiguous package name without ecosystem prefix — may match wrong package or return partial results
- OSV.dev upstream unavailability — real-time query may fail or time out if Google OSV API is down
- Rate limiting or payment failure — x402 micropayment not processed, request rejected

## 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://workflows.agentdiet.dev/v1/maven-vuln-scanner)

## Output

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