# 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 polymarket-odds.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).

Queries Google OSV.dev live vulnerability data for a given package and returns active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust crate ecosystems.

## 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-d2a40c22 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need real-time, live CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust/crates.io ecosystems sourced directly from Google OSV.dev. Prefer it over static NVD snapshots or offline databases when freshness matters — e.g. during CI/CD pipelines, pre-deploy audits, or agent-driven dependency triage. It is especially useful when you need both the CVE identifier and the patched version in a single call.

## Known failure modes

- Package not found in OSV.dev database — returns empty or null vulnerability list
- Invalid package identifier format (e.g. missing ecosystem prefix) — returns validation error
- OSV.dev upstream unavailable — returns gateway or timeout error
- No vulnerabilities found for package — returns empty advisories array (not an error)
- Unsupported ecosystem specified — returns error indicating supported ecosystems

## 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://polymarket-odds.agentdiet.dev/v1/epss-scanner)

## Output

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