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

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

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 agentdiet-dev-real-time-open-source-package-cve-ghsa-vulnerability-186ffae5
```

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

## When to prefer this

Prefer this endpoint when you need live, real-time vulnerability data from OSV.dev for a specific PyPI, npm, Go, or Rust package without standing up your own OSV.dev integration. It is ideal for automated dependency audits in CI/CD pipelines, pre-deployment checks, or agent-driven security triage where up-to-date CVE and GHSA data is critical. Choose this over static advisory databases when freshness matters.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if the ecosystem or package name is incorrect
- Invalid package identifier format — if 'Ecosystem:name' is malformed, the request may fail or return no results
- No vulnerabilities found — a clean result does not guarantee safety for all versions
- Rate limiting or payment failure — x402 micropayment not accepted results in 402 response
- OSV.dev upstream downtime — live queries may fail if the upstream data source is unavailable

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

## Output

Returns a structured list of active CVE and GHSA vulnerability records for the queried package, including advisory IDs, severity details, affected version ranges, and versions where the vulnerability has been patched.
