# RadhikaChain UTXO Set Statistics

> RadhikaChain UTXO Set Statistics is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $1.0296/call, status unknown (last checked 2026-09-14).

Returns current UTXO set statistics for a blockchain node, including chain height, total outputs, total amount, and best block hash.

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 radhikachain-utxo-set-statistics-586188f0
```

Example prompt: Pull the current UTXO set stats from RadhikaChain — I need the total number of unspent outputs, total coin amount, and best block hash right now.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call snapshot of UTXO set statistics without setting up an account or subscription. It is ideal for agents that need on-demand blockchain telemetry (coin supply, chain tip, UTXO count) and can pay via USDC on Base. Prefer it over running your own node for lightweight, infrequent queries where infrastructure overhead is not justified.

## Known failure modes

- Node temporarily unavailable: HTTP 503 or timeout
- Payment rejected or insufficient USDC balance via x402: HTTP 402 with payment details
- Invalid or expired x402 payment token: HTTP 401
- Rate limit exceeded on the facilitator side
- UTXO set still syncing — returned height may lag behind chain tip

## 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 (height), total number of unspent transaction outputs (txouts), bogosize estimate of UTXO set size in bytes, best block hash (bestblock), total amount of coins in the UTXO set (total_amount), and a UTXO set hash serialization (hash_serialized_3) for integrity verification.
