# Protocol Radar – Ethereum Client Releases

> Protocol Radar – Ethereum Client 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 of the 10 main Ethereum execution and consensus clients as JSON, including version, release date, days since release, release notes link, and a security/urgency flag.

## Facts

- Endpoint: GET https://aaron-protocol-radar.vercel.app/ethereum/client-releases?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12

- Tags: x402
- Canonical page: https://www.zero.xyz/c/protocol-radar-ethereum-client-releases-81cfec7f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_t5tV1tM7STdKv605sLtHi

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-ethereum-client-releases-81cfec7f
```

Example prompt: Can you pull the latest Ethereum client release info and let me know if any of the execution or consensus clients — like go-ethereum, Lighthouse, or Prysm — have flagged security or urgent upgrades?

## When to prefer this

Choose this endpoint when you need a single, consolidated, structured snapshot of all major Ethereum client release statuses — especially when monitoring for security patches or urgent upgrades across both execution and consensus layers simultaneously. Prefer it over scraping individual GitHub release pages or maintaining multiple monitors for each client separately.

## Known failure modes

- Upstream GitHub/release API unavailable — endpoint may return stale or empty data
- Release notes parsing may miss non-standard security keywords if formatting varies
- Vercel cold-start may add latency on first request
- Paid endpoint: insufficient USDC balance will result in 402 Payment Required error

## How this service works

Latest releases of the 10 main Ethereum clients as JSON: execution (go-ethereum, Nethermind, Besu, Erigon, Reth) and consensus (Lighthouse, Prysm, Teku, Nimbus, Lodestar). Version, date, days since release, link to notes, and a plain keyword flag when notes mention security or urgent upgrades.

## Output

A JSON array of up to 10 objects, one per Ethereum client (5 execution: go-ethereum, Nethermind, Besu, Erigon, Reth; 5 consensus: Lighthouse, Prysm, Teku, Nimbus, Lodestar), each containing the client name, latest version string, release date, number of days since release, a URL to the release notes, and a plain-text keyword flag if the release notes mention security or urgent upgrade language.
