## 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 evm-wallet-nonce-lookup-bfcf5a5a
```

Example prompt: What's the current transaction nonce for the wallet 0xAbC1234567890abcdef1234567890abcdef123456 on the Base network?

## When to prefer this

Use this endpoint when you need the current nonce for an EVM wallet address before constructing or signing a transaction, or when verifying how many transactions an address has sent. Supports Ethereum, Base, Polygon, Arbitrum, and Optimism. Requires no API key — pay $0.002 USDC per call via x402 on Base mainnet.

## Known failure modes

- Invalid or malformed wallet address (not 0x-prefixed or not 42 characters) returns an error
- Unsupported network value returns a validation error
- Network RPC unavailable or timeout causes a service error
- Address with no transaction history returns nonce of 0

## How this service works

Returns the current nonce (confirmed transaction count) and pending nonce for any EVM wallet address. Supports Ethereum, Base, Polygon, Arbitrum, and Optimism. Use the pending nonce when building new transactions. $0.002/call — 33% below comparable market rate.

## Output

The current nonce (transaction count) for the specified EVM wallet address on the requested network, indicating how many transactions have been sent from that address and what nonce value to use for the next transaction.
