# 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 serp-extract.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.

## Facts

- Endpoint: GET https://serp-extract.agentdiet.dev/v1/epss-scanner?utm_source=zero.xyz
- Price: $0.01/call
- Payment: MPP
- Status: unknown

- Activations on Zero: 0
- Provider: serp-extract.agentdiet.dev
- Website: https://serp-extract.agentdiet.dev
- Canonical page: https://www.zero.xyz/c/serp-extract-agentdiet-dev-real-time-open-source-package-cve-ghsa-ffa4d1f3
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cDoXwZUGBVoinm9WdqV0h

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 serp-extract-agentdiet-dev-real-time-open-source-package-cve-ghsa-ffa4d1f3
```

Example prompt: Check if the PyPI package 'requests' has any active CVEs or GHSA advisories, and tell me what the patched versions are.

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. It is preferable to static or cached vulnerability databases when freshness matters, or when you need CVE and GHSA advisory details together with patched version recommendations in a single call.

## Known failure modes

- Invalid package identifier format returns an error or empty result
- Package not found in OSV.dev database returns no vulnerabilities (not necessarily safe)
- Ecosystem prefix mismatch (e.g. wrong casing) may yield no results
- OSV.dev API downtime causes request failure
- Rate limiting or payment failure results in HTTP 402 response

## 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://serp-extract.agentdiet.dev/v1/epss-scanner)

## Output

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