# 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, EPSS scores, and patched versions for any 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-47947695
```

Example prompt: Can you scan the PyPI requests package for any active CVEs or GHSA advisories and tell me which versions have patches available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence for open-source packages across PyPI, npm, Go modules, or Rust crates, backed by Google OSV.dev's continuously updated advisory database. Prefer this over static or cached vulnerability databases when freshness of CVE and GHSA data is critical — for example, during CI/CD pipeline checks, dependency audits, or agent-driven security workflows.

## Known failure modes

- Unknown or misspelled package name returns empty or error response
- Ecosystem prefix omitted may cause ambiguous resolution across ecosystems
- OSV.dev upstream downtime or rate limits may cause request failures
- Very new packages with no advisories return empty vulnerability lists
- Malformed 'Ecosystem:name' format may result in a validation 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/epss-scanner)

## Output

Returns a structured response listing active CVEs, GHSA advisory identifiers, vulnerability severity details (including EPSS scores), affected version ranges, and recommended patched versions for the queried open-source package.
