## 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`):

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call lookup of a wallet's ETH balance specifically on the Base (Coinbase L2) network, without setting up your own RPC node or indexer. Ideal for AI agents that need lightweight, on-demand balance checks as part of a workflow (e.g. verifying funds before a transaction) and are already operating in a USDC/x402 payment environment.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Wallet with zero balance returns 0.0 ETH and 0 wei (not an error)
- Network or RPC connectivity issues may cause timeout or 5xx errors
- HTTP 402 returned if payment in USDC is not provided or insufficient
- Rate limiting if too many requests are made in a short window

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

Returns a JSON object confirming the wallet address queried, the resource type ('base-eth-balance'), the balance expressed in ETH (decimal) and wei (integer), and a generated_at UTC timestamp indicating when the balance was fetched.
