# GitHub Repository License, Dependency & Supply-Chain Security Auditor

> GitHub Repository License, Dependency & Supply-Chain 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 2026-10-23).

Evaluates a GitHub repository for license risk, maintenance velocity, stars/forks, and supply-chain security before code execution or integration.

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-license-dependency-d5e70e40 -d '<json body>'
```

Example prompt: Before I integrate langchain-ai/langgraph into our project, can you audit it for license risk, supply-chain security issues, and check how actively it's maintained?

## When to prefer this

Choose this endpoint when you need a pre-integration or pre-execution security gate specifically for GitHub repositories — covering license compliance, supply-chain risk, and maintenance health in a single call. Prefer this over manual GitHub inspection or generic vulnerability scanners when you need a structured, agent-consumable risk report that combines multiple signals (license, stars, maintenance velocity, dependency security) simultaneously. Ideal for CI/CD pipelines, AI coding agents evaluating third-party code, and open source adoption workflows.

## Known failure modes

- Invalid or non-existent repo format returns an error (repo must be in owner/name format)
- Private repositories inaccessible to the auditor return an access error
- GitHub API rate limits may cause transient failures
- Very new repositories with minimal history may return incomplete maintenance metrics
- Network timeouts for large repositories with many dependencies

## 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/workflows/code-release-security-gate)

## Output

Returns a structured security report covering: license type and risk level, maintenance velocity indicators (commit frequency, last update), repository popularity signals (stars, forks), supply-chain security findings (dependency vulnerabilities, flagged packages), and an overall risk assessment for the repository.
