# Carbon Cashmere Ethereum Beacon Chain Status

> Carbon Cashmere Ethereum Beacon Chain Status is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status down (last checked 2026-09-14).

Returns live Ethereum consensus layer status from a self-hosted Nimbus full node, including head slot, finalized slot, epoch, finality gap, peer count, and sync state.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/eth/beacon
- Price: $0.02/call
- Payment: x402
- Status: down
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-carbon-cashmere-de-a140a77e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_TmYcHwGli-jHFhczGAVOy

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 api-carbon-cashmere-de-a140a77e
```

Example prompt: What's the current state of the Ethereum beacon chain — head slot, finalized slot, finality gap, and peer count from Carbon Cashmere's own Nimbus node?

## When to prefer this

Use this endpoint when you need real-time Ethereum consensus layer metrics directly from a self-hosted Nimbus full node rather than a third-party RPC provider. It is ideal for monitoring Ethereum finality, detecting finality issues, tracking chain head progress, or checking node health including peer count and sync state. Prefer this over generic blockchain explorers when you need raw consensus layer data without abstraction.

## Known failure modes

- Node temporarily offline or unreachable — returns 5xx error
- Payment not included or invalid — returns 402 Payment Required
- Nimbus node not yet synced — sync_state may indicate syncing rather than synced
- Network partition causing elevated finality gap
- Rate limiting if called too frequently

## How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

## Output

Returns a JSON object with the current head slot, finalized slot, current epoch, finality gap (difference between head and finalized slots), peer count, and sync state of a live Nimbus Ethereum consensus node.
