## When to prefer this

Choose this endpoint when you need historical on-chain data specifically from Base mainnet and are comfortable with micropayment-per-call x402 pricing ($0.05 USDC). Prefer it over generic blockchain explorers when you need structured intelligence data suitable for AI agent consumption rather than raw transaction lookups.

## Known failure modes

- Insufficient USDC payment via x402 protocol returns HTTP 402 Payment Required
- Asset or address not found on Base mainnet returns empty dataset
