# Protocol Radar - x402 Protocol Updates

> Protocol Radar - x402 Protocol Updates 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 a JSON snapshot of recent x402 protocol changes, including merged GitHub commits, latest repository tags, and current npm versions of all @x402 and @coinbase/x402 packages.

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-x402-protocol-updates-681ec04d
```

Example prompt: What are the latest x402 protocol updates — any recently merged changes in the repo, new tags, and the current npm versions of packages like @x402/core, @x402/evm, and @coinbase/x402?

## When to prefer this

Use this endpoint when you need a consolidated, real-time snapshot of the x402 protocol ecosystem — GitHub activity plus npm package versions — in a single call. Prefer this over manually querying GitHub and npm separately when you want structured JSON with links ready for agent consumption.

## Known failure modes

- GitHub API rate limiting may cause stale or missing commit/tag data
- npm registry unavailability could result in missing package version fields
- Network timeout if upstream APIs are slow
- Stale data if the endpoint's cache has not refreshed since last GitHub/npm poll

## How this service works

x402 protocol updates as JSON: recently merged changes in the x402 Foundation repository (formerly coinbase/x402), latest tags, and current npm versions of the @x402 packages (core, evm, express, fetch, extensions) and @coinbase/x402. Read live from GitHub and npm, with links.

## Output

A JSON object containing: recently merged pull requests from the x402 Foundation GitHub repository (formerly coinbase/x402), latest repository tags, and current npm version numbers with links for @x402/core, @x402/evm, @x402/express, @x402/fetch, @x402/extensions, and @coinbase/x402.
