# PulseScanner Beacon Chain Stats

> PulseScanner Beacon Chain Stats is a paid API for AI agents from x402.pulsescanner.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-21).

Returns aggregate beacon-chain statistics for PulseChain (chain ID 369), including validator counts by status, participation rates, and the epoch at which the data was read.

## Facts

- Endpoint: GET https://x402.pulsescanner.io/v2/beacon/stats?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/pulsescanner-beacon-chain-stats-8da3600d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_U621VMwyrCHoEyhYsILFC

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 pulsescanner-beacon-chain-stats-8da3600d
```

Example prompt: What are the current beacon chain stats for PulseChain — how many validators are active, pending, and exiting, and what's the participation rate for the latest epoch?

## When to prefer this

Choose this endpoint when you need a high-level aggregate snapshot of PulseChain's beacon chain — total validator counts by status, participation rates, and current epoch — rather than details about a single validator. Use this for dashboards, monitoring, or network health checks. For individual validator data, use the single-validator endpoint instead.

## Known failure modes

- Invalid or unsupported 'window' query parameter value returns an error
- Network or RPC timeout if PulseChain node is unreachable
- Payment not processed (x402 payment required) results in 402 response
- Rate limiting if too many calls made in rapid succession

## How this service works

Beacon-chain totals: validator counts by status, participation, and the epoch they were read at. PulseChain (chain id 369). $0.003 USDC per call.

## Output

Returns a JSON object containing beacon-chain aggregate totals for PulseChain (chain ID 369): validator counts broken down by status (e.g. active, pending, exited, slashed), overall participation metrics, and the epoch number at which the snapshot was taken.
