# 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 in real time to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate package.

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-7d101172
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and tell me which version I should upgrade to if it does?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for open source packages across PyPI, npm, Go, or Rust ecosystems, especially when you need CVE and GHSA advisories with patched version recommendations in a single call. Prefer it over static databases or periodic scans when freshness of vulnerability data matters, such as in CI/CD pipelines, pre-deployment audits, or live dependency monitoring.

## Known failure modes

- Package not found in OSV.dev — returns empty or error response if the ecosystem or package name is invalid
- Unsupported ecosystem — ecosystems outside PyPI, npm, Go, and crates.io may return no results
- Network/upstream failure — OSV.dev API downtime may cause timeouts or 5xx errors
- Malformed package identifier — missing or incorrect 'Ecosystem:name' format may yield no results
- Payment failure — x402 micropayment not fulfilled results in 402 response

## 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/zero-day-advisories)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, severity ratings, affected version ranges, and recommended patched versions for the queried package, sourced live from Google OSV.dev.
