# 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, $0.01/call, status unknown (last checked 2026-10-23).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust 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 x402-audit-agentdiet-dev-real-time-open-source-package-cve-ghsa-ac2a525e -d '<json body>'
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories, and tell me what patched version I should upgrade to?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust packages, especially when you want CVE IDs and GHSA advisories together with patched version recommendations in a single API call. Prefer it over static vulnerability databases when freshness matters, or when building automated dependency auditing pipelines for AI agents that need up-to-date security intelligence without maintaining a local advisory database.

## Known failure modes

- Package not found in OSV.dev database — returns empty advisory list or 404-style response
- Invalid ecosystem prefix causes query failure — returns validation error
- OSV.dev upstream unavailable — returns upstream timeout or service error
- Malformed package identifier format — returns schema validation error
- Package exists but has no known vulnerabilities — returns empty results (not an error)

## 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/npm-vuln-scan)

## Output

Returns a structured response listing active CVEs and GHSA security advisories for the queried package, including vulnerability IDs, descriptions, severity information, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
