# 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, $0.015000/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev live intelligence for a named package and returns active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, and Rust ecosystems.

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-cdb8a236 -d '<json body>'
```

Example prompt: Check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, and tell me which versions are patched.

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA advisory data from the authoritative Google OSV.dev database for PyPI, npm, Go, or Rust packages. It is ideal for CI/CD pipeline security gates, dependency audits, or agent-driven supply chain risk assessments where freshness matters and you want structured advisory output including patched versions without building your own OSV.dev integration.

## Known failure modes

- Package not found in OSV.dev database — returns empty vulnerability list or 404-style error
- Malformed package identifier (missing ecosystem prefix or invalid name) — returns validation error
- OSV.dev upstream unavailable — returns upstream timeout or service error
- No known vulnerabilities for the package — returns empty advisories array
- Unsupported ecosystem specified — returns error indicating supported ecosystems

## 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)

## Output

Returns a structured object listing active CVE identifiers, GHSA advisory IDs, affected version ranges, severity ratings, and available patched versions for the queried package, sourced live from Google OSV.dev.
