## How to call it through Zero

```

Example prompt: What's the current on-chain balance for wallet address 0x1234...abcd — can you pull that from RagRadar?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call on-chain balance lookup for wallet addresses on Base, Arbitrum, or Solana without maintaining your own RPC infrastructure. Ideal for AI agents needing real-time wallet data with x402 micropayment billing at $0.01 per call — no subscription required.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Unsupported chain or address format may return empty or error result
- Address with no activity may return zero balance or minimal metadata
- Network latency or chain RPC downtime may cause timeout or failure
- Incorrect address format for the target chain (e.g. EVM address on Solana endpoint) causes lookup failure
