# 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 x402-audit.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 PyPI, npm, Go, or Rust crate packages.

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 x402-audit-agentdiet-dev-real-time-open-source-package-cve-ghsa-22bf9999
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems — particularly when you want CVE and GHSA advisory data sourced directly from Google OSV.dev without maintaining your own vulnerability database. Prefer this over static SBOM scanners when freshness matters or when you need to check a single package on demand in an agent workflow.

## Known failure modes

- Package not found in OSV.dev — returns empty or null advisory list
- Invalid ecosystem prefix causes query failure (e.g. unrecognized ecosystem name)
- OSV.dev upstream unavailable causing timeout or 5xx error
- Malformed package identifier format returns validation error
- No vulnerabilities found returns empty array (not an error, but may be misread as a 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://x402-audit.agentdiet.dev/v1/cve-lookup)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, severity information, and recommended patched versions for the queried package from the live OSV.dev database.
