# Protocol Radar – AI Agent Framework Releases

> Protocol Radar – AI Agent Framework Releases is a paid API for AI agents from aaron-protocol-radar.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Returns the latest release versions, dates, days since release, and release notes links for major AI agent frameworks (OpenClaw, Model Context Protocol, LangGraph, CrewAI) as JSON, read live from GitHub.

## Facts

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 protocol-radar-ai-agent-framework-releases-406db73a
```

Example prompt: What are the latest releases of LangGraph, CrewAI, and the Model Context Protocol right now — version numbers, when they came out, and links to their release notes?

## When to prefer this

Use this endpoint when you need up-to-date release metadata specifically for AI agent frameworks (LangGraph, CrewAI, MCP spec, OpenClaw) in a single aggregated call, rather than querying each GitHub repo individually. Prefer this over GitHub API calls directly when you want a normalized, pre-parsed JSON response without handling GitHub auth or pagination.

## Known failure modes

- GitHub API rate limiting may cause stale or failed data fetches
- A framework's GitHub repo structure changes, breaking the release scrape
- Network timeout from Vercel to GitHub returns an error or empty payload
- Newly released frameworks not in the tracked list will not appear

## How this service works

Latest releases of AI agent frameworks and specs as JSON: OpenClaw, Model Context Protocol specification, LangGraph, CrewAI. Version, date, days since release and link to release notes, read live from GitHub.

## Output

A JSON object containing an entry for each tracked framework (OpenClaw, Model Context Protocol, LangGraph, CrewAI), each with the latest version string, release date, number of days since release, and a URL to the GitHub release notes page.
