# 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 prompt-guard.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev for active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate packages in real time.

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 prompt-guard-agentdiet-dev-real-time-open-source-package-cve-ghsa-ea7d33fa
```

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 have patches?

## When to prefer this

Use this endpoint when you need real-time, authoritative vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. Prefer it over static SCA databases when freshness matters — it pulls live CVE and GHSA data. It is especially useful in CI/CD pipelines, dependency auditing workflows, or agent-driven security reviews where up-to-date patch information is critical.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-like response
- Invalid ecosystem prefix causes parsing error — requires correct format like 'PyPI:requests' or 'npm:lodash'
- OSV.dev upstream outage or rate limiting — may return 503 or timeout
- Ambiguous package name without ecosystem prefix may resolve to wrong ecosystem
- Network or payment (x402) failure returns 402 payment required or 5xx 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://prompt-guard.agentdiet.dev/v1/npm-vuln-scan)

## Output

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