## 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 manylives-onchain-base-wallet-balance-lookup-5af52f45
```

Example prompt: Check the on-chain balance for wallet 0x4200000000000000000000000000000000000006 on the Base network — I need to see its ETH balance, stablecoin holdings, and how many transactions it has made.

## When to prefer this

Use this endpoint when an AI trading agent needs a quick, pay-per-call lookup of a Base network wallet's ETH and stablecoin balances plus transaction history without setting up an account. Prefer this over full node RPC calls when you want verifiable, pre-packaged on-chain data in a simple REST format, especially in agent workflows where cost-per-call micropayment billing via x402 is acceptable.

## Known failure modes

- Missing or malformed wallet address returns an error — the 'wallet' query param is required and must be a valid 0x address
- Invalid 0x address format may return an error or empty/zero balances
- Network latency or Base RPC unavailability may cause timeouts
- Payment failure (insufficient USDC for the $0.002 x402 micropayment) will block the call

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON object with the wallet address, its ETH balance as a decimal string, USD stablecoin balance as a decimal string, and the total number of transactions the wallet has made on the Base network.
