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

Queries Google OSV.dev in real-time to return active CVEs, GHSA advisories, and patched versions for PyPI, npm, Go, or Rust packages

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 hn-pulse-agentdiet-dev-real-time-open-source-package-cve-ghsa-cdef52cf -d '<json body>'
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories right now, and tell me which version fixes them?

## When to prefer this

Choose this endpoint when you need live, authoritative vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when OSV.dev's real-time database is preferable to stale cached advisory feeds. Ideal for CI/CD pipelines, dependency vetting workflows, and agent-driven security audits where up-to-date CVE and GHSA data matters and a $0.01 per-call cost is acceptable.

## Known failure modes

- Package not found in OSV.dev database — returns empty advisory list or 404-equivalent
- Invalid ecosystem prefix causes validation error (e.g. 'pip:requests' instead of 'PyPI:requests')
- OSV.dev upstream timeout or unavailability results in service error
- Malformed package identifier (missing name or unsupported ecosystem) triggers input schema validation failure
- Payment failure via x402 returns 402 before query is executed

## 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://hn-pulse.agentdiet.dev/v1/pypi-vuln-scan)

## Output

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