# 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-57b30c8a
```

Example prompt: Can you check the PyPI package 'requests' for any active CVEs or GHSA security advisories and tell me what patched version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems sourced directly from Google OSV.dev. Prefer it over static SBOM tools or offline databases when freshness of CVE and GHSA data matters, such as before deploying software or auditing new dependencies.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Invalid ecosystem prefix causes a malformed query error
- OSV.dev upstream unavailability causes timeout or 503
- Ambiguous package name without ecosystem prefix may resolve to wrong ecosystem
- No vulnerabilities found does not necessarily mean the package is safe — only known advisories are returned

## 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/pypi-vuln-scan)

## Output

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