# 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 token-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev for active CVE and GHSA vulnerability advisories, severity scores, and patched versions for PyPI, npm, Go, or Rust 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 token-intel-agentdiet-dev-real-time-open-source-package-cve-ghsa-fd9fec00
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories right now, and tell me which version has the fixes?

## 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 need CVE IDs, GHSA advisories, EPSS scores, and patched version recommendations in a single call. Prefer this over static NVD queries when freshness matters, or when working with open-source ecosystems that OSV.dev covers comprehensively.

## Known failure modes

- Package not found in the specified ecosystem — returns empty results or 404-style error
- Invalid ecosystem prefix causes query failure — must use supported formats like PyPI:name or npm:name
- OSV.dev upstream unavailability causes delayed or failed response
- Malformed package identifier (missing colon separator) returns validation error
- Package with no known vulnerabilities returns empty advisory list, which may be mistaken for 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://token-intel.agentdiet.dev/v1/epss-scanner)

## Output

Returns a list of active vulnerabilities for the queried package including CVE IDs, GHSA advisory identifiers, EPSS scores, severity ratings, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
