# 47620 XNO Nano Block Receipt Verification

> 47620 XNO Nano Block Receipt Verification is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Verifies whether a specific Nano (XNO) block hash has been confirmed and cemented on-chain, returning confirmation status, subtype, account, amount, and block metadata.

## 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 47620-xno-nano-block-receipt-verification-e09a5f09
```

Example prompt: Can you check whether this Nano (XNO) block hash is confirmed and cemented on-chain: A170D51B94E00371ACE76E35AC81DC9405D5D04D48A2AC83CCAF4F9B0B9E8B3A? I need to know if the transfer actually landed.

## When to prefer this

Use this endpoint when you need a definitive, pay-per-call receipt check for a specific Nano (XNO) transaction by block hash — no signup or API key required, just USDC via x402. Prefer this over running your own Nano node or integrating a heavier blockchain SDK when you only need to verify individual transfers on demand. Ideal for agents automating payment-gated workflows where proof of XNO receipt is the sole requirement.

## Known failure modes

- Invalid or malformed block hash (not 64 hex characters) returns an error
- Block hash not found on the Nano network returns confirmed: false
- Live public node unavailable may cause cemented status to be indeterminate
- Payment failure via x402 results in 402 response with no data returned
- Network timeout if Nano node is slow to respond

## How this service works

Independently confirms whether a Nano (XNO) block actually landed on-chain. Given a 64-hex block hash, returns confirmed (bool), subtype, account, amount (raw + XNO), height, successor, and whether a live public node reports it cemented — plus the block's confirmation data. The buyable unit is 'tell me definitively whether this specific transfer happened', chain-agnostic. Pay-per-call USDC via x402; no signup, no API key.

## Output

A JSON object with fields: ok (bool indicating API success), confirmed (bool indicating on-chain confirmation), subtype (e.g. send/receive), account (Nano address), amount in raw units, amount in XNO, block height, successor block hash, cemented status as reported by a live public node, and full block confirmation data.
