## 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 ethereum-live-balances-sample-8f530bba
```

Example prompt: What are the current ETH and USDC balances on Ethereum mainnet for the wallet 0x5D8b58bAdE65318bC95e2EAd24e6F0E2b042Aa78?

## When to prefer this

Choose this endpoint when you need live, real-time ETH and ERC-20 token balance data from Ethereum mainnet without running your own node. Prefer this over static explorers when you need programmatic, machine-readable balance data for automation or monitoring. Use the free sample to validate integration before purchasing the paid multi-address version.

## Known failure modes

- Ethereum node unavailable — service returns 503 or timeout
- Cloudflare tunnel down — endpoint unreachable, returns connection error
- Rate limiting on free sample endpoint — returns 429
- Demo address has zero balances — returns valid response with 0 values
- Malformed response if upstream RPC node is syncing

## How this service works

Free live Ethereum ETH and USDC sample for the service receiver. Purchase native ETH plus one to three ERC-20 balances at GET /ethereum-live-balance?address=0x5D8b58bAdE65318bC95e2EAd24e6F0E2b042Aa78 for $0.0029.

## Output

Returns a live balance snapshot for a fixed demo Ethereum address, including native ETH balance and one or more ERC-20 token balances (e.g. USDC), reflecting real-time on-chain state from Ethereum mainnet.
