# 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 2026-10-23).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for any PyPI, npm, Go, or Rust 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-3114fe06 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open source packages across PyPI, npm, Go modules, or Rust crates. It is ideal for automated dependency auditing, CI/CD security gates, or agent-driven supply chain risk checks where up-to-date CVE and GHSA data is required rather than a cached or periodic snapshot.

## Known failure modes

- Package not found in the specified ecosystem — returns empty or error response
- Invalid ecosystem prefix causes request rejection
- OSV.dev upstream unavailable causing timeout or degraded response
- Malformed package identifier format returns validation error
- Package with no known vulnerabilities returns empty advisory list

## 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/cve-lookup)

## Output

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