# 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 live vulnerability data for a named open-source package 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-f7c68141
```

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

## When to prefer this

Choose this endpoint when you need live, real-time vulnerability data from Google OSV.dev for PyPI, npm, Go modules, or Rust crates — particularly when you want a single API call that normalizes CVE and GHSA advisories together with patched version information, without running a local scanner or maintaining a vulnerability database.

## Known failure modes

- Unknown or misspelled package name returns empty results or a not-found error
- Unsupported ecosystem prefix causes a validation error
- OSV.dev upstream unavailability causes a timeout or 502 error
- Malformed package identifier format (missing colon separator) returns a 400 bad request
- 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/cargo-vuln-scan)

## Output

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