## How to call it through Zero

```sh
zero fetch --capability proofsignal-wallet-snapshot-82a9fea3
```

Example prompt: Can you pull a full wallet snapshot for 0x742d35Cc6634C0532925a3b8D4C9B7F1a6E1Dc9 on Base — I need to know whether it's an EOA or contract, its ETH and USDC balances, its nonce, and what block we're on right now?

## When to prefer this

Choose this endpoint when you need a single-call summary of a wallet's readiness on Base mainnet — especially when you need multiple data points (ETH balance, USDC balance, nonce, account type, and block number) simultaneously and want to avoid multiple round-trips. Prefer this over individual balance endpoints when you need to quickly assess whether a wallet can participate in a transaction or DeFi action. It is purpose-built for Base mainnet and is not suitable for other EVM chains.

## Known failure modes

- Missing or malformed address parameter returns a 400 error
- Non-0x-prefixed address fails validation
- Address not found on Base mainnet may return zero balances rather than an error
- Network congestion may cause slightly stale block number data
- x402 payment failure or insufficient USDC for the $0.001 fee returns a 402 Payment Required response
- Cloudflare tunnel downtime may result in connection errors

## How this service works

Base wallet readiness snapshot: checksum address, EOA or contract classification, ETH and native USDC balances, transaction nonce, and current block in one response.

## Output

A JSON object containing the checksummed wallet address, chain ID, network name, account type (EOA or contract), ETH balance as a string, native USDC balance as a string, transaction count/nonce as a number, current block number, and a checkedAt timestamp — all reflecting the live state of the address on Base mainnet at the moment of the call.
