## 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 preflight-agentdiet-dev-real-time-open-source-package-cve-ghsa-63926b5c
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data directly from Google OSV.dev for a specific open-source package across PyPI, npm, Go modules, or Rust crates. Prefer it over static advisory databases when freshness matters — especially for zero-day and recently disclosed CVEs. It is ideal for CI/CD pipeline security checks, pre-deployment audits, and dependency vetting workflows where up-to-the-minute advisory data is required.

## Known failure modes

- Package not found in the specified ecosystem — returns empty or error response
- Invalid package format (missing ecosystem prefix for ambiguous names) — may return error or incorrect results
- OSV.dev upstream unavailability causing timeout or degraded response
- Rate limiting or payment failure (HTTP 402) blocking the request
- Package name typos leading to no results silently

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

## Output

Returns a structured response listing active CVE identifiers, GHSA advisory IDs, severity information, affected version ranges, and available patched versions for the specified open-source package, sourced live from Google OSV.dev.
