## How to call it through Zero

Example prompt: Can you pull the on-chain balance for wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 using Nansen's data?

## When to prefer this

Use this endpoint when you need Nansen-powered on-chain balance data for a specific wallet address, especially when smart money intelligence context is important. Prefer this over generic blockchain RPC calls when you want Nansen's curated, enriched data. Use the sibling /balances endpoint if you need multi-wallet batch queries.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported blockchain network not covered by Nansen
- Payment not processed (x402 payment required at $0.06 USDC per call)
- Empty result if wallet has no recorded balance in Nansen's dataset
- Rate limiting or quota exceeded returns an error response
