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-auditor-ef95b67b
```

Example prompt: Before I add langchain-ai/langgraph as a dependency, can you audit that GitHub repo for license risk, supply-chain security issues, and check if it's actively maintained?

## When to prefer this

Choose this endpoint when an AI coding agent needs to vet a third-party GitHub repository before integrating it as a dependency, when performing open source license compliance checks, or when evaluating supply-chain security risk of a specific repo prior to code execution. Preferred over generic GitHub API calls when you need a consolidated security+license+maintenance report in a single call.

## Known failure modes

- Invalid or non-existent GitHub repo format returns an error
- Private or inaccessible repositories may not be auditable
- Rate limiting from GitHub API could cause partial results
- Repos with no license file may return unknown license risk
- Payment failure via x402 may block access to the endpoint

## 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/code-security)

## Output

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