# 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 defi-yield.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 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 defi-yield-agentdiet-dev-real-time-open-source-package-cve-ghsa-2ffab925
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, and tell me what 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 PyPI, npm, Go, or Rust crate packages, especially when you need CVE IDs, GHSA advisories, and patched version recommendations in a single call. Prefer it over static NVD snapshots or local lockfile scanners when freshness matters. It is ideal for CI/CD pipelines, pre-release audits, or agent-driven supply chain risk checks where up-to-date advisory data is critical.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result that may be misread as 'safe'
- Invalid ecosystem prefix causes query failure (e.g. misspelling 'PyPI' as 'pypi')
- OSV.dev upstream API unavailable — returns 5xx or timeout
- No vulnerabilities found returns empty list, not an error — agent must distinguish 'none found' from 'lookup failed'
- Rate limiting or payment failure returns 402 requiring USDC micropayment

## 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://defi-yield.agentdiet.dev/v1/cve-lookup)

## Output

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