# 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 hn-pulse.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 hn-pulse-agentdiet-dev-real-time-open-source-package-cve-ghsa-326e9fd3
```

Example prompt: Can you check if the npm package lodash has any active 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 — especially when you need CVE and GHSA advisory IDs alongside patched version recommendations. Prefer this over static SCA databases when freshness and live intelligence matter, such as in CI/CD pipelines, pre-deployment audits, or agent-driven dependency reviews.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if the ecosystem/name combination is invalid
- Malformed package identifier (e.g. missing ecosystem prefix for ambiguous names) — may return no results or an error
- OSV.dev upstream unavailability — may return a 5xx or timeout
- No known vulnerabilities — returns an empty advisory list, which could be confused with an error
- Rate limiting or payment failure ($0.015/call via x402) — returns HTTP 402 if payment is not provided

## 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://hn-pulse.agentdiet.dev/v1/cve-lookup)

## Output

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