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

Queries Google OSV.dev live vulnerability data for a named open-source package and returns active CVEs, GHSA advisories, 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 preflight-agentdiet-dev-real-time-open-source-package-cve-ghsa-4119283f
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA advisories and tell me which versions have fixes?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data directly from Google OSV.dev for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is ideal for CI/CD pipelines, dependency audits, or agent-driven security reviews where up-to-date CVE and GHSA advisory coverage matters. Prefer it over static NVD lookups or bundled SCA databases when freshness and ecosystem breadth are priorities.

## Known failure modes

- Package not found in OSV.dev (unknown or misspelled package name)
- Ecosystem prefix not recognized (must be PyPI, npm, Go, or crates.io)
- OSV.dev upstream API unavailable or rate-limited causing delayed or empty response
- No vulnerabilities found (clean package) — may return empty advisory list, not an error
- Malformed package identifier format causing query failure

## 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://preflight.agentdiet.dev/v1/epss-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory references, severity metadata, affected version ranges, and recommended patched versions for the queried open-source package, sourced live from Google OSV.dev.
