# GitHub Repo Health Score Checker

> GitHub Repo Health Score Checker is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Analyzes a GitHub repository and returns a 0-100 health score with grade (abandoned/stale/okay/healthy/thriving) based on commit activity, contributors, license, CI, tests, and an LLM verdict.

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 x402-deployer-x402-deployer-workers-dev-40fe6801 -d '<json body>'
```

Example prompt: Can you check the health of the GitHub repo https://github.com/expressjs/express and tell me if it's still actively maintained — give me the score, grade, and the AI verdict?

## When to prefer this

Use this endpoint when you need a structured, scored assessment of a GitHub repository's health and maintainability, especially when deciding whether to adopt a dependency, audit an open-source library, or flag abandoned projects. It combines quantitative metrics (commits, contributors, CI, tests, license) with an LLM verdict in a single call, making it more comprehensive than manually inspecting GitHub stats.

## Known failure modes

- Repository not found or private — returns error if the repo URL is invalid or inaccessible
- GitHub API rate limit exceeded — may return error or degraded data
- Repo has no activity data — sparse repos may result in low confidence scores
- Invalid URL format — returns validation error if the repo URL is malformed
- Network timeout fetching GitHub data — returns timeout error

## How this service works

GitHub repo health score / open-source maintainability checker. 0-100 score + grade (abandoned/stale/okay/healthy/thriving). Commit activity, contributors, license, CI, tests. Plus LLM verdict.

## Output

Returns a 0-100 numeric health score, a categorical grade (abandoned, stale, okay, healthy, or thriving), metrics on commit activity, number of contributors, presence of a license, CI configuration, and tests, plus an LLM-generated verdict summarizing the overall maintainability of the repository.
