# 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 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 prompt-guard-agentdiet-dev-real-time-open-source-package-cve-ghsa-535a77e6
```

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

## When to prefer this

Choose this endpoint when you need live, up-to-date vulnerability data for open source packages across PyPI, npm, Go, or Rust ecosystems sourced directly from Google OSV.dev. Prefer it over static databases or offline scanners when real-time CVE and GHSA accuracy matters, such as in CI/CD pipelines, pre-deployment audits, or agent-driven dependency reviews. It is particularly useful for single-package lookups with a pay-per-call model rather than subscribing to a full vulnerability feed.

## Known failure modes

- Package not found in the specified ecosystem — returns empty or error response
- Malformed package identifier format — requires 'Ecosystem:name' or plain 'name' format
- OSV.dev upstream unavailable — may return timeout or 5xx error
- No known vulnerabilities found — returns empty advisories list (not an error)
- Payment failure via x402 protocol — request rejected before processing

## 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/zero-day-advisories)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, affected version ranges, severity information, and recommended patched versions for the queried package, sourced live from Google OSV.dev.
