## 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 on-chain-native-balance-lookup-by-chain-and-address-c4886f5c
```

Example prompt: What's the native token balance for wallet address 0xAbCd1234... on Base right now?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call native token balance lookup across any of 38 supported chains without managing your own RPC infrastructure. It is especially useful for multi-chain coverage via Pocket Network's decentralized gateway, supporting Ethereum, Solana, BSC, peaq natively plus 34 EVM chains. Prefer it over self-hosted RPC when cost-per-call billing ($0.008 USDC) is acceptable and you need broad chain coverage without API key management.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or empty response
- Malformed wallet address (wrong format for the chain) returns an error
- Address with zero balance returns native: 0, which may be confused with an error
- RPC node temporarily unavailable for a specific chain causes timeout or 503
- Payment not settled in USDC via x402 returns 402 Payment Required
- Rate limiting if metered quota exceeded

## How this service works

Real-device, multi-region site verification with screenshot proof, live Pocket Network Shannon relay-demand/tokenomics/validator-security data, and on-chain RPC snapshots across 38 chains -- Ethereum, Solana, BSC, and peaq natively, plus 34 more EVM chains via Pocket Network's free public gateway (Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea, Scroll, Gnosis, and more) -- 54 metered x402 routes, priced and settled per call in USDC. Migrating to Acurast decentralized cloud compute for censorship-resistant hosting -- stay tuned.

## Output

A JSON object containing the queried chain identifier, the chain's human-readable name, the queried wallet address, and the native token balance as a decimal number (e.g. {"chain":"base","chainName":"Base","address":"0x...","native":1.2345}).
