# 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 live OSV.dev vulnerability intelligence for a given 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-89138f0a
```

Example prompt: Check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and let me know which versions have been patched.

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from the authoritative OSV.dev database across PyPI, npm, Go, and Rust crate ecosystems — especially in agentic pipelines that require up-to-date CVE and GHSA advisories rather than cached or static snapshots. Prefer it over static NVD lookups when ecosystem-specific patched version guidance is needed.

## Known failure modes

- Invalid or unrecognized package identifier returns an error or empty result
- Ecosystem prefix missing or malformed (e.g. 'PyPI:' vs 'pypi:') may cause lookup failure
- Package not found in OSV.dev database returns no vulnerabilities (not necessarily safe)
- OSV.dev upstream API downtime causes request failure
- Payment (x402) not fulfilled results in HTTP 402 response

## 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 details, severity ratings, affected version ranges, and recommended patched versions for the queried open-source package, sourced live from Google OSV.dev.
