Example prompt: Can you check ChainRay's whale tracker for the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum and tell me what large on-chain movements or whale activity it's been involved in?

## When to prefer this

Use this endpoint when you need to identify whether a specific wallet address exhibits whale-level behavior, trace large on-chain movements, or gather intelligence on significant token holders across 46 supported blockchains. Prefer this over generic blockchain explorers when you need structured, agent-ready intelligence rather than raw transaction data.

## Known failure modes

- Invalid or malformed wallet/contract address returns 400 error
- Unsupported chain identifier returns 400 or 404
- Address not found on specified chain returns empty result or 404
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many requests in short succession
- Network-level timeout if chain data is temporarily unavailable

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns whale activity data for the specified address including large token transfers, notable on-chain movements, holding patterns, and intelligence signals that indicate whether the wallet qualifies as a whale — contextualized for the specified blockchain network.
