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

Queries live OSV.dev to return active CVEs, GHSA advisories, EPSS scores, 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 mcp-compiler-agentdiet-dev-real-time-open-source-package-cve-ghsa-6dbd2b40
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, 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 the authoritative OSV.dev database rather than a static or cached snapshot. It is ideal for CI/CD security gates, dependency audits before deployment, or any workflow requiring up-to-date CVE and GHSA advisory data across PyPI, npm, Go modules, and Rust crates. Prefer this over general web search when you need structured, machine-readable vulnerability records with specific version ranges and patch recommendations.

## Known failure modes

- Package not found in OSV.dev (unknown ecosystem or misspelled name returns empty or error)
- Invalid ecosystem prefix causes parsing failure (e.g. 'pypi:requests' vs 'PyPI:requests')
- OSV.dev upstream API timeout or outage results in failed response
- Payment not processed (HTTP 402 if x402 payment fails)
- Package has no known vulnerabilities — returns empty advisory list, 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://mcp-compiler.agentdiet.dev/v1/epss-scanner)

## Output

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