# GitHub Repository Dependency & License Security Auditor

> GitHub Repository Dependency & License Security Auditor is a paid API for AI agents from prompt-guard.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Audits a GitHub repository for license risk, maintenance health, popularity metrics, and supply-chain security vulnerabilities before using or executing its code.

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 prompt-guard-agentdiet-dev-github-repository-dependency-license-ab52997c
```

Example prompt: Before I add langchain-ai/langgraph to my project, can you audit its GitHub repo for license risks, supply-chain security issues, and whether it's actively maintained?

## When to prefer this

Choose this endpoint when an AI coding agent needs to vet a third-party GitHub repository for safety before integrating or executing its code — particularly for license compliance checks, supply-chain security scanning, and maintenance health assessment. It is purpose-built for pre-integration due diligence on open source repos and is more convenient than manually querying GitHub's API, Snyk, or OSS Index separately.

## Known failure modes

- Invalid repo format (not owner/name) returns a validation error
- Non-existent or private repository returns a not-found or access-denied error
- GitHub API rate limits may cause intermittent failures or incomplete results
- Repositories with no dependency manifests may return partial supply-chain data
- Payment not fulfilled (HTTP 402) if x402 payment header is missing or invalid

## How this service works

Evaluates any GitHub repository for license risk, maintenance velocity, stars/forks, and supply-chain security before code execution. (Live x402 v2, IETF MPP & MCP endpoint at https://prompt-guard.agentdiet.dev/v1/dependency-audit)

## Output

Returns a structured report covering license risk classification, maintenance velocity indicators (commit frequency, last commit date), repository popularity signals (stars, forks), and supply-chain security findings (dependency vulnerabilities, known CVEs or suspicious packages) for the specified GitHub repository.
