# 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 in real-time 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-4b1143d1
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories, and tell me which version I should upgrade to if it's vulnerable?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. Prefer it over static advisory databases when you need up-to-date CVE and GHSA coverage without maintaining your own vulnerability feed. Ideal for automated dependency audits, CI/CD security gates, and agent-driven DevSecOps workflows where freshness of vulnerability intelligence matters.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result for unknown/misspelled package names
- Invalid ecosystem prefix causes query failure — package must use correct format like 'PyPI:name' or 'npm:name'
- OSV.dev upstream unavailability — live dependency means latency spikes or errors if Google OSV.dev is down
- Payment failure — x402 micropayment not authorized, returning HTTP 402 before scan executes
- Missing required 'package' parameter returns a validation 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/pypi-vuln-scan)

## Output

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