# 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 for a given open-source package and returns active CVEs, GHSA advisories, and patched versions across PyPI, npm, Go, and Rust ecosystems.

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-fba27068
```

Example prompt: Can you check the PyPI package 'requests' for any active CVEs or GHSA security advisories and tell me if there are patched versions available?

## When to prefer this

Choose this endpoint when you need live, up-to-date vulnerability data (CVEs and GHSA advisories) for open-source packages across PyPI, npm, Go, or Rust ecosystems sourced directly from Google OSV.dev. It is ideal for automated dependency auditing, CI/CD security gates, or pre-deployment checks where freshness of vulnerability data matters. Prefer it over static SCA databases when you need real-time advisory coverage with patched-version guidance.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Unsupported ecosystem prefix causes a bad-request error
- OSV.dev upstream unavailability results in a timeout or 5xx response
- Missing required 'package' parameter returns a 400 validation error
- Package with no known vulnerabilities returns an empty advisory list, which 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://defi-yield.agentdiet.dev/v1/npm-vuln-scan)

## Output

Returns a structured object listing all active CVEs and GHSA advisories for the queried package, including vulnerability IDs, severity ratings, affected version ranges, and available patched versions sourced live from Google OSV.dev.
