# 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 live vulnerability intelligence for PyPI, npm, Go, or Rust packages and returns active CVEs, GHSA advisories, and patched versions.

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-b3adf520
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for a specific open source package across PyPI, npm, Go, or Rust ecosystems — especially when you need CVE and GHSA advisory details with patched version guidance in a single call. Prefer this over static databases when currency of data matters for CI/CD pipelines, pre-deployment audits, or agent-driven dependency reviews.

## Known failure modes

- Package not found in any supported ecosystem — returns empty advisory list or 404
- Invalid package identifier format — returns validation error requesting 'Ecosystem:name' format
- OSV.dev upstream unavailable — returns 503 or timeout error
- Unsupported ecosystem specified — returns error indicating supported ecosystems (PyPI, npm, Go, crates.io)
- Payment not provided or insufficient — returns HTTP 402 requiring x402 USDC payment

## 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/ghsa-advisories)

## Output

Returns a list of active CVEs and GHSA advisories affecting the queried package, including severity levels, affected version ranges, fixed/patched versions, and advisory descriptions sourced live from Google OSV.dev.
