# Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev)

> 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 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-open-source-package-cve-ghsa-498d390b
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories, and tell me which version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data sourced directly from Google OSV.dev for PyPI, npm, Go, or Rust crate packages. Prefer it over static advisory databases when you need the most current CVE and GHSA data, or when checking specific package identifiers across multiple ecosystems. Ideal for CI/CD pipeline security gates, pre-deployment dependency audits, or agent-driven security triage workflows.

## Known failure modes

- Package not found in OSV.dev database — returns empty advisory list or 404-equivalent
- Invalid ecosystem prefix or malformed package identifier — may return error or no results
- OSV.dev upstream unavailable — endpoint may time out or return a service error
- Package name without ecosystem prefix may be ambiguous across ecosystems — results may be incomplete
- No known vulnerabilities exist for the package — returns empty results, not 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/zero-day-advisories)

## Output

Returns a structured object containing active CVEs, GitHub Security Advisory (GHSA) IDs, affected version ranges, severity ratings, and recommended patched versions for the queried open-source package, sourced live from Google OSV.dev.
