# 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 to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate 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-9b77ee65
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories right now, and tell me which versions are patched?

## When to prefer this

Choose this endpoint when you need real-time, up-to-date CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems, especially when you want a single API call rather than integrating directly with OSV.dev yourself. It is ideal for CI/CD security gating, dependency auditing, and agent-driven security workflows that require live intelligence rather than cached or static databases.

## Known failure modes

- Invalid or unrecognized package name returns empty results or an error
- Unsupported ecosystem prefix causes a validation error
- OSV.dev upstream unavailability may result in timeout or 503 error
- Malformed 'Ecosystem:name' format causes a 400 bad request
- Package with no known vulnerabilities returns an empty advisory list, which may be confused with an error

## 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/npm-vuln-scan)

## Output
