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

Queries Google OSV.dev for active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate package.

## 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-1bbc7a64
```

Example prompt: Check if the PyPI package 'requests' has any active CVEs or GHSA advisories and tell me what versions have been patched.

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust crate packages — especially when you want CVE and GHSA advisory details including patched version information in a single call, without maintaining your own vulnerability database.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if the ecosystem/name is invalid or not indexed
- Malformed package identifier (e.g. missing ecosystem prefix) may return an error or unexpected results
- OSV.dev upstream unavailability could cause timeout or degraded response
- No vulnerabilities found is a valid empty result, not an error
- Rate limiting or payment failure may block access at the x402 layer

## 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://polymarket-odds.agentdiet.dev/v1/vuln-scanner)

## Output

Returns a structured list of active CVEs and GHSA advisories affecting the specified package, including advisory IDs, severity details, affected version ranges, and the versions in which vulnerabilities have been patched, sourced live from Google OSV.dev.
