# 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 onchain-risk.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 given PyPI, npm, Go, or Rust crate package and returns 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 onchain-risk-agentdiet-dev-real-time-open-source-package-cve-ghsa-542734cd
```

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

## When to prefer this

Choose this endpoint when you need real-time, authoritative CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates. It is backed directly by Google OSV.dev, making it more up-to-date than static NVD snapshots or cached databases. Prefer it for supply chain security checks, CI/CD pipeline audits, or pre-deployment dependency reviews where freshness of vulnerability intelligence matters.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style response
- Malformed package identifier format causes validation error
- OSV.dev upstream API unavailability results in timeout or 503
- Unsupported ecosystem prefix returns an error or no results
- Rate limiting or payment failure due to x402 micropayment issues

## 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://onchain-risk.agentdiet.dev/v1/ghsa-advisories)

## Output

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