> PulseScanner Validator Detail 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).

## 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-validator-detail-a1399ce6
```

Example prompt: Pull up the current status, balance, and activation window for PulseChain validator index 4271 — I want to know if it's active and what its balance is right now.

## When to prefer this

Use this endpoint when you need detailed information about a single specific PulseChain validator by its integer index, including status, balance, and activation timing. Prefer this over the list endpoint when you already know the validator index and want precise, low-latency data for one validator rather than paginated results.

## Known failure modes

- Invalid or out-of-range validator index returns a 404 or empty result
- Non-numeric or malformed idx path parameter causes a 400 bad request
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Network or indexer downtime may cause 503 or timeout errors
- Very recently registered validators may not yet appear if the indexer lags behind the chain head

## How this service works

One validator: its status, balance and activation window. PulseChain (chain id 369). $0.003 USDC per call.

## Output

Returns a JSON object for the specified validator including its index, current status (e.g. active, pending, exited), current balance in Gwei or native units, and activation epoch or window on the PulseChain beacon chain (chain ID 369).
