## 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 saylor-innovations-evm-nonce-lookup-bsc-3bbb7d41
```

Example prompt: What's the current on-chain nonce for BSC address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on the Binance Smart Chain?

## When to prefer this

Choose this endpoint when you need the on-chain transaction nonce specifically for a BSC (Binance Smart Chain) address, especially before signing and broadcasting a transaction, deploying a contract, or auditing account activity. Prefer it over Ethereum mainnet nonce endpoints when working exclusively with BNB Chain.

## Known failure modes

- Invalid or malformed address returns an error response
- Non-existent address (no transactions) returns nonce of 0
- Network or RPC node outage may cause timeout or 5xx errors
- Incorrect chain queried if address exists on multiple EVM chains but nonce differs

## How this service works

EVM Nonce (bsc). BNB Chain (BSC) account nonce for any address: confirmed nonce and pending nonce (a gap means transactions are still waiting in the mempool). Use it before sending a transaction or to detect a pending one.

## Output

Returns the current transaction nonce (account transaction count) for the specified address on the BSC EVM network, typically as an integer representing how many transactions have been sent from that address.
