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-d1479774 -d '<json body>'
```

Example prompt: Check if the npm package lodash has any active CVEs or GHSA security advisories right now, and tell me what patched versions are available.

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability intelligence from OSV.dev for PyPI, npm, Go, or Rust (crates.io) packages, especially when you want CVE and GHSA advisory data with patched version details in a single call. Prefer this over static databases when freshness matters or when you need to check a dependency just before deployment or code review.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Unsupported ecosystem prefix causes parsing failure
- OSV.dev upstream unavailability results in a timeout or 502 error
- Package with no known vulnerabilities returns an empty advisories list (not an error)
- Malformed 'Ecosystem:name' format may cause a 400 bad request

## 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/npm-vuln-scan)

## Output

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