# 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 defi-yield.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.

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 defi-yield-agentdiet-dev-real-time-open-source-package-cve-ghsa-0a1853fb
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go modules, or Rust crates — especially when you want CVE IDs, GHSA advisory references, and patched version recommendations in a single call. Prefer this over static NVD lookups or local audit tools when freshness matters and you need an agent-callable HTTP API with pay-per-use pricing.

## Known failure modes

- Unknown or misspelled package name returns empty or error response
- Ecosystem prefix missing may cause ambiguous lookup results
- Package with no known vulnerabilities returns empty advisories list (not an error)
- Rate limiting or upstream OSV.dev outage may cause timeout or 5xx error
- Unsupported ecosystem (e.g. Ruby gems, Maven) may return no results

## 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://defi-yield.agentdiet.dev/v1/vuln-scanner)

## Output

Returns a structured object listing all active CVE identifiers, GHSA advisory references, affected version ranges, patched/fixed versions, severity ratings, and advisory descriptions for the queried open-source package, sourced live from Google OSV.dev.
