## 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 radhikachain-utxo-set-telemetry-2c6686a4
```

Example prompt: Pull the current UTXO set snapshot from RadhikaChain — I need the block height, total output count, total coin amount, and the UTXO set hash for the chain tip.

## When to prefer this

Choose this endpoint when you need a pay-per-call, no-subscription UTXO set snapshot with cryptographic integrity fields (hash_serialized_3) and you are operating on the Base chain with USDC for micropayments. Prefer it over self-hosted node calls when you lack a full node, or over subscription APIs when you need infrequent, one-off queries without account setup.

## Known failure modes

- Payment not included or invalid x402 USDC payment on Base → 402 Payment Required
- Node temporarily out of sync → stale or missing block height data
- Service unavailable during maintenance → 503 or timeout
- Invalid payment scheme version → rejected by facilitator

## How this service works

Telemetria de cadena, inteligencia de defensa y computo verificable (Halo2, Nova, Plonky3). Pago por peticion en USDC nativo en Base (eip155:8453) mediante x402 v2 scheme exact; sin cuenta ni suscripcion. Catalogo canonico: GET /.well-known/x402.

## Output

A JSON object containing: current block height (integer), total UTXO count (txouts), UTXO set bogosize in bytes, best block hash (hex string), total coin amount across all UTXOs (decimal), and a serialized UTXO set hash (hash_serialized_3). Costs $0.198 USDC per call via x402 payment on Base.
