# 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 agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev in real time 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 agentdiet-dev-real-time-open-source-package-cve-ghsa-vulnerability-c20c9402
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and tell me what patched version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data for a specific open-source package across PyPI, npm, Go modules, or Rust crates. It is ideal for CI/CD pipelines, dependency audits, or agent-driven security workflows that require live CVE and GHSA data rather than cached snapshots. Prefer it over static SBOMs or periodic scans when freshness of vulnerability intelligence is critical.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Invalid ecosystem prefix — malformed package identifier causes error
- OSV.dev upstream timeout or unavailability — may return error or stale data
- Package with no known vulnerabilities returns empty advisories list
- Ambiguous package name without ecosystem prefix may match wrong ecosystem

## 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://agentdiet.dev/v1/maven-vuln-scanner)

## Output

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