# 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 live CVE and GHSA vulnerability advisories for a named open-source package across PyPI, npm, Go, and Rust ecosystems, returning active vulnerabilities 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-ec6533d4
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data for open-source packages from PyPI, npm, Go modules, or Rust crates, particularly when you want CVE and GHSA advisory details along with patched version guidance sourced directly from Google OSV.dev rather than a static or cached database.

## Known failure modes

- Package not found in the specified ecosystem returns empty or error response
- Invalid ecosystem prefix causes lookup failure
- OSV.dev upstream unavailability may result in timeout or 5xx error
- Ambiguous package name without ecosystem prefix may return incorrect results
- Rate limiting or payment failure (HTTP 402) blocks the request

## 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/epss-scanner)

## Output

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