# 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 mesh.agentdiet.dev, paid per call via MPP, $0.01/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, and Rust (crates.io) 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 mesh-agentdiet-dev-real-time-open-source-package-cve-ghsa-619b162f
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories right now, and tell me which version has the fixes?

## When to prefer this

Choose this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates, especially when OSV.dev is your authoritative source. Prefer it over static advisory databases when you need real-time patched version information for automated dependency audits or CI/CD pipelines.

## Known failure modes

- Unknown or misspelled package name returns empty vulnerability list or error
- Unsupported ecosystem prefix causes a validation error
- Transient OSV.dev API unavailability causes a timeout or 5xx response
- Package name without ecosystem prefix may default to npm or produce ambiguous results
- Rate limiting or payment failure returns HTTP 402 requiring USDC micropayment

## 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://mesh.agentdiet.dev/v1/npm-vuln-scan)

## Output

Returns a structured object containing a list of active CVE and GHSA advisory identifiers for the queried package, affected version ranges, severity information, and the earliest patched version available, sourced live from Google OSV.dev.
