## How to call it through Zero

```sh
zero fetch --capability chainray-cross-chain-address-lookup-c15fe3c6
```

Example prompt: Can you pull up the cross-chain activity for the wallet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e across all blockchains ChainRay supports?

## When to prefer this

Use this endpoint when you need to understand a wallet or contract's presence and activity across multiple blockchain networks in a single call, rather than querying each chain individually. Ideal for cross-chain portfolio analysis, multi-chain due diligence, or tracing an address's footprint across the 46+ chains ChainRay supports.

## Known failure modes

- Invalid or malformed address returns 400 error
- Address not found on any supported chain returns empty result
- Unsupported chain parameter returns error
- Payment failure via x402 protocol blocks request
- Rate limiting may occur under high volume
- Network-specific RPC outages may yield partial results
