# GitHub Repository Supply Chain & License Security Auditor

> GitHub Repository Supply Chain & 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).

Analyzes a GitHub repository for license risk, dependency supply-chain vulnerabilities, maintenance velocity, and popularity signals before code adoption or execution.

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-supply-chain-license-9818df31
```

Example prompt: Before I integrate langchain-ai/langgraph into our codebase, can you do a full supply-chain and license audit on it — check for dependency vulnerabilities, license risk, and whether it's actively maintained?

## When to prefer this

Choose this endpoint when an AI coding agent or developer needs to vet a GitHub repository before adoption, code execution, or inclusion in a software supply chain. It is especially valuable for pre-flight checks on open source dependencies, license compliance reviews, and security audits — covering aspects that generic code search or GitHub browsing tools do not automatically surface.

## Known failure modes

- Invalid or non-existent repository owner/name returns an error
- Private repositories that are inaccessible to the scanner return an access error
- GitHub API rate limits may cause timeouts or partial results
- Repos with no detectable dependency manifests may return incomplete supply-chain data
- Payment failure (HTTP 402) if x402 payment is not properly configured

## 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/repo-supply-chain-scan)

## Output

Returns a structured report covering license type and risk level, maintenance velocity metrics (commit frequency, last commit date), repository popularity signals (stars, forks), and supply-chain security findings including known vulnerable dependencies.
