# Maven/Java Security Advisory Brief

> Maven/Java Security Advisory Brief is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns an LLM-generated digest summarizing the most severe new Maven/Java GitHub Security Advisories (GHSA) in a given time window

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/ghsa-maven/brief
- Price: $0.25/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/maven-java-security-advisory-brief-ff3c47ce
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_oi6SWFlzUZTwwm_hz7AGj

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 maven-java-security-advisory-brief-ff3c47ce
```

Example prompt: Give me an LLM-written brief on the most severe new Maven and Java security advisories from the last 7 days — I want to know which vulnerabilities are most critical and how many advisories were analyzed.

## When to prefer this

Use this endpoint when you need a human-readable, LLM-synthesized narrative summary of Maven/Java security advisories rather than raw advisory data. Prefer this over raw GHSA lookups when you want a quick high-level briefing on severity and risk rather than structured per-advisory details. Ideal for security digest emails, developer alerts, or automated monitoring pipelines targeting Java/Maven ecosystems specifically.

## Known failure modes

- No new advisories in window returns empty or minimal brief
- Invalid date-time format for 'since' parameter returns validation error
- LLM generation failure may fall back to template-based output (generatedBy: 'template')
- Payment failure (402) if x402 payment of $0.25 USDC is not provided
- Upstream GHSA data unavailability may cause stale or failed response

## How this service works

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

## Output

Returns a JSON object containing: 'brief' — a natural language narrative digest of the most severe Maven/Java advisories written by an LLM; 'generatedBy' — either 'llm' or 'template'; and 'basedOnChanges' — an integer count of advisory changes that were analyzed to produce the digest.
