# GitHub Repository Supply-Chain Security Auditor

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

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

## 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 preflight-agentdiet-dev-github-repository-supply-chain-security-auditor-e8e8fb82
```

Example prompt: Can you do a full supply-chain security audit on the langchain-ai/langgraph GitHub repo — check its license risk, how actively it's maintained, and any dependency vulnerabilities before I add it to my project?

## When to prefer this

Use this endpoint when an AI coding agent needs to vet a GitHub repository before integrating it as a dependency, executing its code, or recommending it to users — especially when license compliance, supply-chain integrity, or maintenance health are concerns. Prefer this over generic package vulnerability scanners (e.g. OSV.dev) when you need a holistic repo-level view including community signals and license risk, not just CVE data for a specific package version.

## Known failure modes

- Invalid or non-existent repository owner/name returns an error
- Private repositories inaccessible via GitHub public API return a failure
- GitHub API rate limiting may cause transient failures
- Malformed repo parameter (not in owner/name format) triggers validation error
- Repositories with no dependency manifest files may return partial results

## 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://preflight.agentdiet.dev/v1/repo-supply-chain-scan)

## Output

Returns a structured security report covering: license type and risk level, repository maintenance velocity (commit frequency, recency), popularity signals (stars, forks), and supply-chain security assessment of the repository and its dependencies.
