# GitHub Repository Supply-Chain Security & License Auditor

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

Scans any GitHub repository for license risk, dependency vulnerabilities, maintenance health, and supply-chain security signals before integrating or executing 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 onchain-risk-agentdiet-dev-github-repository-supply-chain-security-ad1c19db
```

Example prompt: Before I add langchain-ai/langgraph as a dependency, can you do a full supply-chain and license security audit on that GitHub repo and tell me if there are any red flags?

## When to prefer this

Choose this endpoint when an AI coding agent or developer needs to vet a GitHub repository before adding it as a dependency, executing its code, or integrating it into a project. Ideal for supply-chain due diligence, license compliance checks, and open-source procurement reviews. Prefer over generic web search when you need structured, normalized security and maintenance signals rather than raw search results.

## Known failure modes

- Invalid or non-existent repository format returns an error (repo must be in owner/name format)
- Private or inaccessible repositories may return limited or no data
- GitHub API rate limiting may cause intermittent failures
- Repositories with no dependency manifests may return incomplete supply-chain data
- Payment not processed (HTTP 402) if x402 funds are insufficient

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

## Output

Returns a structured report covering the repository's license type and associated risk level, maintenance velocity indicators (commit frequency, last commit date), popularity signals (stars, forks, watchers), and supply-chain security findings including dependency vulnerabilities and suspicious patterns.
