Example prompt: Pull the full on-chain token transfer history for Ethereum address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e so I can see every ERC-20 token that's been sent to or from it.

## When to prefer this

Choose this endpoint when you need on-chain Ethereum token transfer history for a specific wallet address and want a simple REST call billed per-use via x402 micropayment, without managing your own Ethereum node or blockchain indexer subscription. Ideal for lightweight agent workflows that need occasional address-level transfer lookups on Ethereum mainnet.

## Known failure modes

- Invalid or malformed Ethereum address returns an error response
- Address with no transfer history returns an empty result set
- Rate limiting or quota exceeded if too many calls are made
- Network timeouts if the Ethereum node or indexer is temporarily unavailable
- Very active addresses with thousands of transfers may return paginated or truncated results
