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

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for any PyPI, npm, Go, or Rust crate 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 workflows-agentdiet-dev-real-time-open-source-package-cve-ghsa-b9362300
```

Example prompt: Check OSV.dev for any active CVEs or GHSA security advisories affecting the PyPI requests package and tell me which versions are patched.

## 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 and GHSA identifiers together with patched version recommendations in a single call. Prefer this over static NVD snapshots or locally cached advisory databases when freshness is critical, such as in CI/CD pipelines or security audits.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style error
- Invalid ecosystem prefix causes a parsing error — e.g. 'PYPI:requests' vs correct 'PyPI:requests'
- OSV.dev upstream unavailability results in a timeout or 502 error
- Ambiguous package name without ecosystem prefix may return results from the wrong ecosystem
- Payment not settled (x402) results in 402 response blocking the query

## 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://workflows.agentdiet.dev/v1/zero-day-advisories)

## Output

Returns a structured list of active vulnerability records for the queried package, including CVE IDs, GHSA advisory identifiers, vulnerability summaries, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
