## 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 sitesignal-npm-latest-release-risk-pack-a2367889
```

Example prompt: Can you pull the npm release risk pack for 'lodash' — I need the latest registry metadata, last week's download numbers, and any known OSV vulnerabilities for its current version before we approve it as a dependency?

## When to prefer this

Choose this endpoint when you need a consolidated snapshot of an npm package's current health — combining registry metadata, popularity signals, and security vulnerability data — in a single call rather than querying npm, download stats, and OSV separately. Ideal for dependency review workflows, supply chain audits, or automated CI/CD gate checks where you want bounded, pre-combined risk intelligence on the latest release specifically.

## Known failure modes

- Package not found on npm registry — returns error or empty result
- Package name typo or scoping error (e.g. missing @ for scoped packages) — returns 404-style failure
- OSV database has no records for the package — vulnerability list may be empty but not an error
- Cloudflare tunnel availability issues causing intermittent 502/503 errors
- Rate limiting or upstream npm/OSV API unavailability causing partial data

## How this service works

Combine current npm registry metadata, last-week downloads, and exact-latest-version OSV records into a bounded release review-priority pack.

## Output

A bundled JSON report containing: current npm registry metadata (version, author, description, license, publish date), last-week download count from the npm registry, and OSV (Open Source Vulnerabilities) records matched to the exact latest version — all combined into a single release review-priority pack.
