# 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 in real time to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-bd0dd4f4
```

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

## When to prefer this

Choose this endpoint when you need real-time CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems. It is backed directly by Google OSV.dev, making it more current than static NVD mirrors. Prefer it for automated dependency auditing, CI/CD security gating, or agent-driven supply chain risk checks where up-to-date patch information is critical.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Unsupported ecosystem prefix causes a validation error
- OSV.dev upstream unavailability leads to a timeout or 503 response
- Malformed 'Ecosystem:name' format may return empty results
- Package with no known vulnerabilities returns an 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/maven-vuln-scanner)

## Output

Returns a structured list of active vulnerabilities for the queried package, including CVE identifiers, GHSA advisory IDs, severity information, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
