# GitHub Repository Security & License Auditor

> GitHub Repository Security & License 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).

Scans a GitHub repository for license risk, maintenance velocity, stars/forks, dependency health, and supply-chain security signals before code execution.

- Price: $0.01/call
- Payment: MPP

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-security-license-auditor-cd57f905
```

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

## When to prefer this

Use this endpoint when an AI coding agent or developer needs to vet a GitHub repository before integrating it as a dependency, executing its code, or including it in a project — specifically when you need a combined view of license risk, maintenance health, and supply-chain security in a single call rather than querying GitHub's API directly or running separate security scanners.

## Known failure modes

- Invalid repo format (not owner/name) returns a validation error
- Private or non-existent repositories cannot be scanned and return a not-found error
- GitHub API rate limiting may cause transient failures
- Payment failure via x402 will block the request
- Repos with no license file may return incomplete license data

## 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/github-scanner)

## Output

Returns a structured report covering the repository's license type and associated legal risk, maintenance velocity indicators (commit frequency, last activity), community signals (stars, forks), and supply-chain security findings including dependency vulnerability signals.
