## When to prefer this

Use this endpoint when you need on-chain transaction history for a specific wallet address across Base, Arbitrum, or Solana. Prefer this over generic block explorers when you need structured, machine-readable data for AI agent pipelines, and when micropayment-based access via x402 is acceptable. Especially useful when cross-chain wallet auditing or DeFi activity analysis is required.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier returns an error or empty result
- Address with no transaction history returns empty list
- Network or RPC timeout for the specified chain
- Micropayment via x402 not fulfilled results in 402 Payment Required response
