## 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 rubygems-security-advisory-digest-ghsa-brief-a6117754

Example prompt: Can you give me an LLM-written digest of the most severe new RubyGems security advisories since January 1, 2025?

## When to prefer this

Use this endpoint when you need a human-readable, LLM-synthesized summary of RubyGems/Ruby security advisories rather than raw advisory data. Ideal for security digests, automated security newsletters, or when a developer wants a quick natural-language briefing on Ruby ecosystem threats. Prefer this over raw GHSA lookups when you want severity-ranked narrative rather than structured data.

## Known failure modes

- No new advisories in window returns a brief with zero changes noted
- Invalid since datetime format returns a 400 error
- Payment not provided or insufficient returns a 402 Payment Required
- Service unavailable or LLM generation failure returns a 503 or 500 error

## How this service works

LLM-written digest of the most severe new RubyGems/Ruby vulnerabilities (CVEs / advisories) in the window and which packages to patch first.

## Output

Returns a JSON object containing a 'brief' field with a natural-language LLM-written summary of the most severe new RubyGems/Ruby GHSA advisories in the window, a 'generatedBy' field indicating whether it was produced by an LLM or template, and a 'basedOnChanges' integer indicating how many advisories were analyzed.
